Question

2x/x+1= 3/x-2 + 1/ x^2-x-2

Answer 1

now when doing this do I need to move things because of the = sign?

Answer 2

Am I reading this equation correctly? \[\frac {2x}{x+1}= \frac{3}{x-2} + \frac{1}{x^2-x-2}\]

Answer 3

yes, for some reason it gives me an error when i use the equation thing

Answer 4

well, can you factor\[x^2-x-2\]

Answer 5

so would it go down to just x^2 on the bottom?

Answer 6

no. Do you know what I mean by factor? what values of a and b would solve this equation?\[x^2-x-2=(x+a)(x+b)\] where we know that a + b = -1 and ab = -2

Answer 7

We are trying to find the LCD (lowest common denominator).
