Solution for (x-3)(2x-4)=12 equation:


Simplifying
(x + -3)(2x + -4) = 12

Reorder the terms:
(-3 + x)(2x + -4) = 12

Reorder the terms:
(-3 + x)(-4 + 2x) = 12

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

Combine like terms: -6x + -4x = -10x
(12 + -10x + 2x2) = 12

Add '-12' to each side of the equation.
12 + -10x + -12 + 2x2 = 12 + -12

Reorder the terms:
12 + -12 + -10x + 2x2 = 12 + -12

Combine like terms: 12 + -12 = 0
0 + -10x + 2x2 = 12 + -12
-10x + 2x2 = 12 + -12

Combine like terms: 12 + -12 = 0
-10x + 2x2 = 0

Solving
-10x + 2x2 = 0
