If a{x+1x−2−x−1x+2 x + 1 x − 2 − x − 1 x + 2 } = 6x. Find a in its simplest form

Question 1 Report

If a{ $\frac{x + 1}{x - 2} - \frac{x - 1}{x + 2}$ } = 6x. Find a in its simplest form

x2 - 1

x2 + 1

x2 + 4

x2 - 4

Answer Details

a{ $\frac{x + 1}{x - 2} - \frac{x - 1}{x + 2}$ } = a{ $\frac{(x + 1) (x + 2) - (x - 1) (x - 2)}{(x - 2) (x + 2)}$ }
= 6
$\frac{6 x}{x^{2} - 4}$ = 6x
a = x2 - 4
