Question about math stuff! yay?

(a+b)(a-b) \n= a^2 - ab + ba - b^2\n= a^2 - b^2 -ab +ab\n= a^2 - b^2

How about "Math -  Does it really add up?"

Yep! The two answers are right :D

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?

What's with the ... ? Is that a space for a number, are you supposed to guess whether to use the + or the x ? I don't get it, I think I'm gonna cry :~(

I posted these sources earlier to someone else who was looking for math help.\n\nGood Luck!!

Is it possible to have 2 equal signs in a problem?\nI am only in algebra but I haven't seen one like that before.\nSorry I couldn't help.

i dunno if i use it correctly but sometimes when i have to do like, a math project i use it to say for example:\n10 to the 6th power but instead of writing it all out i write:\n10^6 \n\nget me?\nhmm. good luck on finding the answer!

simply subtract 7 from both sides. This leave you with\n\nx<_3

Is this trivia, or are you cheating on a test?\n\n+12\n-12\n+5\n-5\n\n\nThat is, if I recall correctly (and I usually do.)

Would you please type your entire math question the way it is presented in your book? Your description is not enough for anyone to answer you correctly. Thanks!

OMG a math riddle I cant seem to answer!!!! :-)  Awesome. I cant sleep because now i want to knwo the anwer. And so i continue to try and solve it.\n\nBest i can come up with is 113  or 240 or 50-something..\nAlso maybe another number in the 100-n-teens\n\nI did find a 1-3-4 pattern aasuming the next number in 1-3-4-1 was a 3 but was unsure of how to continue it. (its1230 in the moring here)\n\nAnd again another possible patter 1-3-4-8 next number would be 16.\n\nI know some may not even know how I came up with these, but I love math and I love a challenge. I have been trying to find any possible correlation in the numbers that I can. \n\nHope someone figures it out. I know I cant wait to see the answer.

Greg is correct for what you posted, but is that 2 after the y supposed to be superscripted as in y-squared? If that's the case:\n\ny^2 = 9.6\ny = sqrt(9.6) = 3.098

With just ! (Factorial), +, -, * and /, it is impossible to get 150 using only 3 5s without the x^2 (Squared) operation (Which means x*x, in case you are in Fifth Grade), or using a '^2' as you say. If you say there is an alternate way, and there really is, then I give up and admit defeat. (I'm sure most others do.) If you are so sure, why don't you post the answer yourself?
