Simplifying
(x + 2)(x + 7) = (x + 3)(x + 2)

Reorder the terms:
(2 + x)(x + 7) = (x + 3)(x + 2)

Reorder the terms:
(2 + x)(7 + x) = (x + 3)(x + 2)

Multiply (2 + x) * (7 + x)
(2(7 + x) + x(7 + x)) = (x + 3)(x + 2)
((7 * 2 + x * 2) + x(7 + x)) = (x + 3)(x + 2)
((14 + 2x) + x(7 + x)) = (x + 3)(x + 2)
(14 + 2x + (7 * x + x * x)) = (x + 3)(x + 2)
(14 + 2x + (7x + x2)) = (x + 3)(x + 2)

Combine like terms: 2x + 7x = 9x
(14 + 9x + x2) = (x + 3)(x + 2)

Reorder the terms:
14 + 9x + x2 = (3 + x)(x + 2)

Reorder the terms:
14 + 9x + x2 = (3 + x)(2 + x)

Multiply (3 + x) * (2 + x)
14 + 9x + x2 = (3(2 + x) + x(2 + x))
14 + 9x + x2 = ((2 * 3 + x * 3) + x(2 + x))
14 + 9x + x2 = ((6 + 3x) + x(2 + x))
14 + 9x + x2 = (6 + 3x + (2 * x + x * x))
14 + 9x + x2 = (6 + 3x + (2x + x2))

Combine like terms: 3x + 2x = 5x
14 + 9x + x2 = (6 + 5x + x2)
