Solution for x(x+12)=(x-4)(x-4) equation:


Simplifying
x(x + 12) = (x + -4)(x + -4)

Reorder the terms:
x(12 + x) = (x + -4)(x + -4)
(12 * x + x * x) = (x + -4)(x + -4)
(12x + x2) = (x + -4)(x + -4)

Reorder the terms:
12x + x2 = (-4 + x)(x + -4)

Reorder the terms:
12x + x2 = (-4 + x)(-4 + x)

Multiply (-4 + x) * (-4 + x)
12x + x2 = (-4(-4 + x) + x(-4 + x))
12x + x2 = ((-4 * -4 + x * -4) + x(-4 + x))
12x + x2 = ((16 + -4x) + x(-4 + x))
12x + x2 = (16 + -4x + (-4 * x + x * x))
12x + x2 = (16 + -4x + (-4x + x2))

Combine like terms: -4x + -4x = -8x
12x + x2 = (16 + -8x + x2)

Add '-1x2' to each side of the equation.
12x + x2 + -1x2 = 16 + -8x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
12x + 0 = 16 + -8x + x2 + -1x2
12x = 16 + -8x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
12x = 16 + -8x + 0
12x = 16 + -8x
