Solution for (x-4)(3x+3)=(x+6)(x-2) equation:


Simplifying
(x + -4)(3x + 3) = (x + 6)(x + -2)

Reorder the terms:
(-4 + x)(3x + 3) = (x + 6)(x + -2)

Reorder the terms:
(-4 + x)(3 + 3x) = (x + 6)(x + -2)

Multiply (-4 + x) * (3 + 3x)
(-4(3 + 3x) + x(3 + 3x)) = (x + 6)(x + -2)
((3 * -4 + 3x * -4) + x(3 + 3x)) = (x + 6)(x + -2)
((-12 + -12x) + x(3 + 3x)) = (x + 6)(x + -2)
(-12 + -12x + (3 * x + 3x * x)) = (x + 6)(x + -2)
(-12 + -12x + (3x + 3x2)) = (x + 6)(x + -2)

Combine like terms: -12x + 3x = -9x
(-12 + -9x + 3x2) = (x + 6)(x + -2)
