(7/12)x^2 = (1/12) - x
-
multiply entire equation by 12 to get rid of fractions
7x^2 = 1 - 12x
rearrange to have equation equal zero
7x^2 + 12x - 1 = 0
use the quadratic equation to solve for x
x = ( -12 +/- sqrt(144+28))/14
x = ( -12 +/- sqrt172)/14**************sqrt172=13.15
x=1.15/14 or -25.15/14
x= .08 or -1.8 approximately
