265x169x521x1022x2 105 Rearrange to get an expression of the

(.265-x)(.169-x)/(5.21x10^-2+2x)² =10.5 Rearrange to get an expression of the form ax²+bx+c=0

Solution

(.265-x)(.169-x)/(5.21x10^-2+2x)^2 =10.5

(0.265 -x)(0.169 -x) = 10.5(5.21 x 10^-2 +2x)^2

0.045461 -0.265x -0.169x +x^2 = 0.0285 +42x^2 + 2.142x

-41x^2 - 2.576x - 0.016961 =0

It is of the form ax^2 +bx +c =0
