Thread: solving for x

can someone help me solve for x. Thanks.

17.5 = .61+x / (.29-x)(.12-x)

(17.5)(.29-x)(.12-x)-(.61+x)= 0

.609 - 7.175x - 17.5 x^2 - (.61 + x) = 0

I got stuck here....

Add/subtract like terms and use the quadratic equation.

-17.5x^2 - 8.175x -.001 = 0

a = -17.5 b = -8.175 c= -.001
