Simplifying
(x + 4)(x + 2) = 8

Reorder the terms:
(4 + x)(x + 2) = 8

Reorder the terms:
(4 + x)(2 + x) = 8

Multiply (4 + x) * (2 + x)
(4(2 + x) + x(2 + x)) = 8
((2 * 4 + x * 4) + x(2 + x)) = 8
((8 + 4x) + x(2 + x)) = 8
(8 + 4x + (2 * x + x * x)) = 8
(8 + 4x + (2x + x2)) = 8

Combine like terms: 4x + 2x = 6x
(8 + 6x + x2) = 8

Add '-8' to each side of the equation.
