Solution for 70=x*(10-2*x)*(10-2*x) equation: 


Simplifying
70 = x(10 + -2x)(10 + -2x)

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

Combine like terms: -20x + -20x = -40x
70 = x(100 + -40x + 4x2)
70 = (100 * x + -40x * x + 4x2 * x)
70 = (100x + -40x2 + 4x3)

Solving
70 = 100x + -40x2 + 4x3

Solving for variable 'x'.

Reorder the terms:
70 + -100x + 40x2 + -4x3 = 100x + -100x + -40x2 + 40x2 + 4x3 + -4x3

Combine like terms: 100x + -100x = 0
70 + -100x + 40x2 + -4x3 = 0 + -40x2 + 40x2 + 4x3 + -4x3
70 + -100x + 40x2 + -4x3 = -40x2 + 40x2 + 4x3 + -4x3

Combine like terms: -40x2 + 40x2 = 0
70 + -100x + 40x2 + -4x3 = 0 + 4x3 + -4x3
70 + -100x + 40x2 + -4x3 = 4x3 + -4x3

Combine like terms: 4x3 + -4x3 = 0
70 + -100x + 40x2 + -4x3 = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(35 + -50x + 20x2 + -2x3) = 0

Ignore the factor 2.
