(x-5)(2x-4)=

Solution for (x-5)(2x-4)= equation:

Simplifying
(x + -5)(2x + -4) = 0

Reorder the terms:
(-5 + x)(2x + -4) = 0

Reorder the terms:
(-5 + x)(-4 + 2x) = 0

Multiply (-5 + x) * (-4 + 2x)
(-5(-4 + 2x) + x(-4 + 2x)) = 0
((-4 * -5 + 2x * -5) + x(-4 + 2x)) = 0
((20 + -10x) + x(-4 + 2x)) = 0
(20 + -10x + (-4 * x + 2x * x)) = 0
(20 + -10x + (-4x + 2x2)) = 0

Combine like terms: -10x + -4x = -14x
(20 + -14x + 2x2) = 0

Solving
20 + -14x + 2x2 = 0
