(x-2)(x+6)=0

Solution for (x-2)(x+6)=0 equation:

Simplifying
(x + -2)(x + 6) = 0

Reorder the terms:
(-2 + x)(x + 6) = 0

Reorder the terms:
(-2 + x)(6 + x) = 0

Multiply (-2 + x) * (6 + x)
(-2(6 + x) + x(6 + x)) = 0
((6 * -2 + x * -2) + x(6 + x)) = 0
((-12 + -2x) + x(6 + x)) = 0
(-12 + -2x + (6 * x + x * x)) = 0
(-12 + -2x + (6x + x2)) = 0

Combine like terms: -2x + 6x = 4x
(-12 + 4x + x2) = 0

Solving
-12 + 4x + x2 = 0
