Please explain? I am hopeless when it comes to maths. -Sighs in shame-

A vertice (or vertex) is the point where two or more lines meet to form an angle or corner. Think of the top of a pyramid.

i'm good at math, but what exactly is the quustion??? there isn't any... what is it, a equation?\nany way you can post it to sciences and mathematics > mathematics, im sure someone there can help you...\n\n>>>ok one minute i'm working on it...\n\n>>>there you go:\nlets do the first: (x-3)(x-1)(x+2)\nfirst we open the last two parentheses as in usual opening, and the (x-3) remains as it is. we get (x-3)[x^2+2x-x-2]\nequals (x-3)(x^2+x-2) then we open the two parentheses left. first we multiply by the first member (x) then the second (-3). then we get:\nx*x^2+x*x+x*(-2)-3*x^2-3*x-3*(-2)\nx^3 + x^2 - 2x -3x^2 -3x + 6\nand finally:\nx^3 -2x^2 -5x + 6\n\nthe second is the same way, i'm doing it, good luck :)\n\n>>>the second: (x-5)(x+1)(x-2)\nfirst we open the last two parentheses as in usual opening, and the (x-5) remains as it is. we get (x-5)[x^2-2x+x-2]\nequals (x-5)(x^2-x-2) then we open the two parentheses left. first we multiply by the first member (x) then the second (-5). then we get:\nx*x^2+x*(-x)+x*(-2)-5*x^2-5*(-x)-5*(-2)\nx^3 -x^2 -2x -5x^2 +5x +10\nand finally:\nx^3 -6x^2 +3x + 10\n\ni hope i helped...\n\n>>>oh i leave the first one to the last because i have to leave one of the three, and it really doesn't matter which one i leave. for example on the first i left the first parenthese (x-3)[(x-1)(x+2)] but i could leave the last [(x-3)(x-1)](x+2) or the middle (x-1)[(x-3)(x+2)] and i'd still get the same answer. i have to leave one of the three bcuz i can't open them all together, it's complicated and hard, and by opening two ane leave one it becomes much easier.

I don't really know what you need help on....\n\nCheck out some of the sites below in the source section, or you could just post what in particular is troubling you...\n\n(I can sympathize if you're having trouble with Matrices though... those always have so many places to go wrong.. ugh.)\n\n(PPS: Wikipedia can be very useful for finding out more information, as you can tell from the number of links below.)

What sort of help do you need with fractions? It depends. Or you can try math.com\n\nYou have to look a little to actually find what youre looking for, but mostly its good \n\nHope this helps!  :)

could you aswin please rephrase your question...... i tried understanding, but i have failed......

Yeah, I know what you mean. Read my answer to your first question, too, b/c maybe another teacher might be a better match for you as a tutor.  My daughter is having the same problem as you right now, her teacher is so boring she is killing the class slowly and surely. Used to be my son could tutor her, but he is in college now. I can't help b/c you kids are doing math I never ever heard of.  She tells me that you can go to some websites that give math help, if you google the math term you don't understand.  Good luck and don't give up, please?

Because it's incredibly difficult to "understand" things that are completely untrue. Go ahead, give it a try. Try to "understand" that 1+1=3. Not so easy, is it?

Hi, \n\nI'll help with the first one, the rest are similar so this should help:\n\n8(k+3)=12k-4\n\n8*k +8*3 = 12k - 4\n\n8k + 24 = 12k - 4\n\n8k + 28 = 12k \n\n28 = 4k\n\nk = 28/4 =7\n\nGood Luck!\nMatt\n\nP.S. I think it's ironic that someone who misspells 2/3 of the words in her post is calling someone else retarded. Seriously, is her time that valuable that she needs to abbreviate the word 'your'?

It's many years since I did maths but shouldn't there be an = somewhere? And isn't there normally "y" too? I thought it would be fun to stretch my brain for a change but...Am I being obtuse?

The best place to go for math help online that i found was \nhttp://www.math.com\nI hope its useful to you.  I know people on here can tell you the answers, but if you have a test to take, and want to really learn it, go there.

Wow! was that real math?  Boy i'd better go back to elementary and start all over.  All of you are way too smart for me.

Gopal has the correct answer! \n\nSo... becareful with some other results... and... never use:\n0.833 instead of 5/6... it's a mistake!\n\nFinished Algebra with 19!

maths is just like a game in which sometimes u won sometimes lose. i too lov maths bcoz it is the only subject in which u dont have to mug up anything .simply  just by   understanding it once and practising it regularly anyone can easily score good marks

Changed my mind folks. I thought about the actual question and realised it should be a combination question (geez we can tell who didn't do maths at school - me!)\n\nThe answer is\n\n10 x 9 x 8 = 720 divided by 3 x 2 x 1 = 6\n\nMakes the answer 120.\n\nLet me explainacate - (new word for you there)\n\nThere are ten cd's to choose from when you pull the first, 9 to choose from when you pull the second and 8 to choose from when you select the third.\n\nThen you divide it by 6, because the 3 CD's you did pull out could be listed in 6 different permutations, but they are still the same CD's\neg:\nabc, acb,bac, bca, cab, cba - listed different, but same content.\n\nTherefore, I agree with Tanny - It is a combination question and the answer is 120 for the reason outlined above.\n\n(excuse my previous idiot-ness) (another new word there folks)

I can tell that nobody wants to just do this problem.  There's nothing interesting about it.  It's a typical problem that a stat student does to show understanding.  Get out your textbook and study up how to solve it.

Your computer has a calculator built in.  Failing that, try long division.  You're gonna have to learn how to do it anyway.\n\nSheesh.
