Question

x-1/x+1 = 2x/15

(15)(x-1) = (2x)(x+1)

2x^2-15x+17

do i put this in quadratic formula? i so confused.

Answer 1

First, get your simplification right:

(15)(x-1) = (2x)(x+1)
15x - 15 = 2x^2 + 2x
2x^2 - 13x + 15 = 0

You can use the quadratic formula, but it factors fairly easily:

(2x-3)(x-5) = 0

You can make it from there, I assume.
