Multiply (14 + -2x) * (10 + -2x)
x(14(10 + -2x) + -2x * (10 + -2x)) = 0
x((10 * 14 + -2x * 14) + -2x * (10 + -2x)) = 0
x((140 + -28x) + -2x * (10 + -2x)) = 0
x(140 + -28x + (10 * -2x + -2x * -2x)) = 0
x(140 + -28x + (-20x + 4x2)) = 0

Combine like terms: -28x + -20x = -48x
x(140 + -48x + 4x2) = 0
(140 * x + -48x * x + 4x2 * x) = 0
(140x + -48x2 + 4x3) = 0

Solving
140x + -48x2 + 4x3 = 0
