(x+6)(x-3)=

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

Simplifying
(x + 6)(x + -3) = 0

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

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

Multiply (6 + x) * (-3 + x)
(6(-3 + x) + x(-3 + x)) = 0
((-3 * 6 + x * 6) + x(-3 + x)) = 0
((-18 + 6x) + x(-3 + x)) = 0
(-18 + 6x + (-3 * x + x * x)) = 0
(-18 + 6x + (-3x + x2)) = 0

Combine like terms: 6x + -3x = 3x
(-18 + 3x + x2) = 0

Solving
-18 + 3x + x2 = 0

Solving for variable 'x'.
