(4.35E-2 - x)(7.56E-2 -x )
(0.324 + 2x)2

Rearrange to get an expression of the form ax2 + bx + c = 0 and use the quadratic formula (solve for x. This gives:
x = 1.05E-2, 0.143

basically i understand they use the quadratic equation but how did they change that crazy fraction into the quadratic formula?
