Simplifying
m2 + -3m + -18 = (x + -5)(x + -4)

Reorder the terms:
-18 + -3m + m2 = (x + -5)(x + -4)

Reorder the terms:
-18 + -3m + m2 = (-5 + x)(x + -4)

Reorder the terms:
-18 + -3m + m2 = (-5 + x)(-4 + x)

Multiply (-5 + x) * (-4 + x)
-18 + -3m + m2 = (-5(-4 + x) + x(-4 + x))
-18 + -3m + m2 = ((-4 * -5 + x * -5) + x(-4 + x))
-18 + -3m + m2 = ((20 + -5x) + x(-4 + x))
-18 + -3m + m2 = (20 + -5x + (-4 * x + x * x))
-18 + -3m + m2 = (20 + -5x + (-4x + x2))

Combine like terms: -5x + -4x = -9x
-18 + -3m + m2 = (20 + -9x + x2)
