Solution for (10-2x)*(10-2x)*x=72 equation: 


Simplifying
(10 + -2x)(10 + -2x) * x = 72

Reorder the terms for easier multiplication:
x(10 + -2x)(10 + -2x) = 72

Multiply (10 + -2x) * (10 + -2x)
x(10(10 + -2x) + -2x * (10 + -2x)) = 72
x((10 * 10 + -2x * 10) + -2x * (10 + -2x)) = 72
x((100 + -20x) + -2x * (10 + -2x)) = 72
x(100 + -20x + (10 * -2x + -2x * -2x)) = 72
x(100 + -20x + (-20x + 4x2)) = 72

Combine like terms: -20x + -20x = -40x
x(100 + -40x + 4x2) = 72
(100 * x + -40x * x + 4x2 * x) = 72
(100x + -40x2 + 4x3) = 72

Solving
100x + -40x2 + 4x3 = 72

Solving for variable 'x'.

Reorder the terms:
-72 + 100x + -40x2 + 4x3 = 72 + -72
