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

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

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

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

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

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

Combine like terms: 3x + -4x = -1x
(-12 + -1x + x2) = -12

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

Reorder the terms:
-12 + 12 + -1x + x2 = -12 + 12

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

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

Solving
-1x + x2 = 0
