Solution for (x+2)(x+6)=12 equation:


Simplifying
(x + 2)(x + 6) = 12

Reorder the terms:
(2 + x)(x + 6) = 12

Reorder the terms:
(2 + x)(6 + x) = 12

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

Combine like terms: 2x + 6x = 8x
(12 + 8x + x2) = 12

Add '-12' to each side of the equation.
12 + 8x + -12 + x2 = 12 + -12
