x1/x+1 = 2x/15
(15)(x1) = (2x)(x+1)
2x^215x+17
do i put this in quadratic formula? i so confused.

First, get your simplification right:
(15)(x1) = (2x)(x+1)
15x  15 = 2x^2 + 2x
2x^2  13x + 15 = 0
You can use the quadratic formula, but it factors fairly easily:
(2x3)(x5) = 0
You can make it from there, I assume. 
thanks very much steve i got it :)
