Solution for 3x(2+2x)=x(5x-5) equation:


Simplifying
3x(2 + 2x) = x(5x + -5)
(2 * 3x + 2x * 3x) = x(5x + -5)
(6x + 6x2) = x(5x + -5)

Reorder the terms:
6x + 6x2 = x(-5 + 5x)
6x + 6x2 = (-5 * x + 5x * x)
6x + 6x2 = (-5x + 5x2)

Solving
6x + 6x2 = -5x + 5x2

Solving for variable 'x'.

Reorder the terms:
6x + 5x + 6x2 + -5x2 = -5x + 5x2 + 5x + -5x2

Combine like terms: 6x + 5x = 11x
11x + 6x2 + -5x2 = -5x + 5x2 + 5x + -5x2

Combine like terms: 6x2 + -5x2 = 1x2
11x + 1x2 = -5x + 5x2 + 5x + -5x2

Reorder the terms:
11x + 1x2 = -5x + 5x + 5x2 + -5x2

Combine like terms: -5x + 5x = 0
11x + 1x2 = 0 + 5x2 + -5x2
11x + 1x2 = 5x2 + -5x2
