Question

3/x^2+x-2 - 1/x^2-1= 7/2x^2+6x+4

Answer 1

You really need to start using parentheses online, to make things clear:

3/(x^2+x-2) - 1/(x^2-1) = 7/(2x^2+6x+4)

Set everything over a common denominator of 2(x-1)(x+1)(x+2). Then, excluding the values of x = -2,-1,1 You just need to find

9-3x = 0
