Simplifying
(x + -3)(x + -6) = (x + -7)(x + 5)

Reorder the terms:
(-3 + x)(x + -6) = (x + -7)(x + 5)

Reorder the terms:
(-3 + x)(-6 + x) = (x + -7)(x + 5)

Multiply (-3 + x) * (-6 + x)
(-3(-6 + x) + x(-6 + x)) = (x + -7)(x + 5)
((-6 * -3 + x * -3) + x(-6 + x)) = (x + -7)(x + 5)
((18 + -3x) + x(-6 + x)) = (x + -7)(x + 5)
(18 + -3x + (-6 * x + x * x)) = (x + -7)(x + 5)
(18 + -3x + (-6x + x2)) = (x + -7)(x + 5)

Combine like terms: -3x + -6x = -9x
(18 + -9x + x2) = (x + -7)(x + 5)

Reorder the terms:
18 + -9x + x2 = (-7 + x)(x + 5)

Reorder the terms:
18 + -9x + x2 = (-7 + x)(5 + x)

Multiply (-7 + x) * (5 + x)
18 + -9x + x2 = (-7(5 + x) + x(5 + x))
18 + -9x + x2 = ((5 * -7 + x * -7) + x(5 + x))
18 + -9x + x2 = ((-35 + -7x) + x(5 + x))
18 + -9x + x2 = (-35 + -7x + (5 * x + x * x))
18 + -9x + x2 = (-35 + -7x + (5x + x2))
