Solution for (30-2x)*(40-2x)*x=2500 equation: 


Simplifying
(30 + -2x)(40 + -2x) * x = 2500

Reorder the terms for easier multiplication:
x(30 + -2x)(40 + -2x) = 2500

Multiply (30 + -2x) * (40 + -2x)
x(30(40 + -2x) + -2x * (40 + -2x)) = 2500
x((40 * 30 + -2x * 30) + -2x * (40 + -2x)) = 2500
x((1200 + -60x) + -2x * (40 + -2x)) = 2500
x(1200 + -60x + (40 * -2x + -2x * -2x)) = 2500
x(1200 + -60x + (-80x + 4x2)) = 2500

Combine like terms: -60x + -80x = -140x
x(1200 + -140x + 4x2) = 2500
(1200 * x + -140x * x + 4x2 * x) = 2500
(1200x + -140x2 + 4x3) = 2500

Solving
1200x + -140x2 + 4x3 = 2500

Solving for variable 'x'.
