Simplifying
(x + 2)(x + 4) = x2 + px + 8

Reorder the terms:
(2 + x)(x + 4) = x2 + px + 8

Reorder the terms:
(2 + x)(4 + x) = x2 + px + 8

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

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

8 + 6x + x2 = 8 + px + x2

Add '-8' to each side of the equation.
8 + 6x + -8 + x2 = 8 + px + -8 + x2

Reorder the terms:
8 + -8 + 6x + x2 = 8 + px + -8 + x2

Combine like terms: 8 + -8 = 0
0 + 6x + x2 = 8 + px + -8 + x2
6x + x2 = 8 + px + -8 + x2

Reorder the terms:
6x + x2 = 8 + -8 + px + x2

Combine like terms: 8 + -8 = 0
6x + x2 = 0 + px + x2
6x + x2 = px + x2

Add '-1x2' to each side of the equation.
6x + x2 + -1x2 = px + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
6x + 0 = px + x2 + -1x2
6x = px + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
6x = px + 0
6x = px

Solving
6x = px
