[(x+1)/(x-1)]-[(x-1)/(x+1)]\n\nFinding LCM of denominator (x-1) and (x+1) gives (x-1)(x+1)\n\nNow making it a like fraction will give,\n=[(x+1)^2 - (x-1)^2] / (x-1)(x+1)\nwe have (x-1).(x+1)=x^2-1\nalso if you expand the numerator and cancell the x^2 and constant 1^2terms\nthe answer is \n=4x/(x^2-1)

Find every number between 101 and 999 that is divisible by 7 and then add them together.  Hmmm......like I really am going to do that.

If you can do basic math (add, subtract, multiply or divide) you can do it. Unless you are going for a Subject Test for Math, then you need to get a study guide available from the test company or online.\n\nGood Luck

1\n\njust do a little bit of trial you will see that the smaller number you use it nears 1.

Begin by teling yourself that there's nothing on this earth that can defeat you. Make a humble return to those things you know about math and begin to gradually work your way back up to the level where you first began having trouble. Believe in yourself, I know you can do it.

Best way to study for a Math test... Do TONS of practice problems for the stuff that will be on the test... just random questions from your assignments that will be covered on the test.  Make sure the answers are in the back of the book... check your answers and if you get them wrong.  Ask your teacher to help you with those you don't know how to do.   If thye give you a practice test DO IT... and find a buddy to study with...\nGood luck on your tests

I remember once having a teacher give us a copy of a multiple choice test, telling us that that would be the EXACT test.\n\nWhat did I do?  I took a Magic Rub eraser and systematically punched holes in it with my mechanical pencil.  Each row of pinpricks would represent an answer to a question.  1 hole for an A, 2 for a B, 3 for a C, and so forth.  If anyone else saw it, they wouldn't suspect anything at all because they wouldn't know the orientation of the rows. How'd I do on the test?  A+!\n\nFor you, I'd say this.  Have your group sit within visible distance of each other's hands.  Whatever signals you use, don't make noise of any sort.  Wave your pencil sideways "x" times to signal the question number.  Nod the pencil up and down "x" times to signal the answer (1 for a, 2 for b,c, or d).  Then have a "reset" signal in case you incorrectly signaled something, maybe scratch your head.

What math test do you take?  I'm in Algebra 1 and I only remember 1 question.  It's impossible.\n\nSomeone has a total of 100 coins in dimes and quarters.  The total value adds up to $14.05. How many quarters does she have?\n\nA) 27 (I chose this-it's a dollar off)\nB) 40\nC) 56\nD) 79 (I forget-it's way too high)\n\nWell, that's all I have.  Bye bye!\n\nThanks to the guy who solved that.  I won't get a zero now!
