(x-3)(x-4)=

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

Simplifying
(x + -3)(x + -4) = 0

Reorder the terms:
(-3 + x)(x + -4) = 0

Reorder the terms:
(-3 + x)(-4 + x) = 0

Multiply (-3 + x) * (-4 + x)
(-3(-4 + x) + x(-4 + x)) = 0
((-4 * -3 + x * -3) + x(-4 + x)) = 0
((12 + -3x) + x(-4 + x)) = 0
(12 + -3x + (-4 * x + x * x)) = 0
(12 + -3x + (-4x + x2)) = 0

Combine like terms: -3x + -4x = -7x
(12 + -7x + x2) = 0

Solving
12 + -7x + x2 = 0

Solving for variable 'x'.
