Solution for 20=(x)(x+5)(x+1) equation: 


Simplifying
20 = (x)(x + 5)(x + 1)

Reorder the terms:
20 = x(5 + x)(x + 1)

Reorder the terms:
20 = x(5 + x)(1 + x)

Multiply (5 + x) * (1 + x)
20 = x(5(1 + x) + x(1 + x))
20 = x((1 * 5 + x * 5) + x(1 + x))
20 = x((5 + 5x) + x(1 + x))
20 = x(5 + 5x + (1 * x + x * x))
20 = x(5 + 5x + (1x + x2))

Combine like terms: 5x + 1x = 6x
20 = x(5 + 6x + x2)
20 = (5 * x + 6x * x + x2 * x)
20 = (5x + 6x2 + x3)

Solving
20 = 5x + 6x2 + x3

Solving for variable 'x'.

Reorder the terms:
20 + -5x + -6x2 + -1x3 = 5x + -5x + 6x2 + -6x2 + x3 + -1x3
