Simplifying
(x + 2)(x + -3) = (x + -4)(x + 5)

Reorder the terms:
(2 + x)(x + -3) = (x + -4)(x + 5)

Reorder the terms:
(2 + x)(-3 + x) = (x + -4)(x + 5)

Multiply (2 + x) * (-3 + x)
(2(-3 + x) + x(-3 + x)) = (x + -4)(x + 5)
((-3 * 2 + x * 2) + x(-3 + x)) = (x + -4)(x + 5)
((-6 + 2x) + x(-3 + x)) = (x + -4)(x + 5)
(-6 + 2x + (-3 * x + x * x)) = (x + -4)(x + 5)
(-6 + 2x + (-3x + x2)) = (x + -4)(x + 5)

Combine like terms: 2x + -3x = -1x
(-6 + -1x + x2) = (x + -4)(x + 5)

Reorder the terms:
-6 + -1x + x2 = (-4 + x)(x + 5)

Reorder the terms:
-6 + -1x + x2 = (-4 + x)(5 + x)

Multiply (-4 + x) * (5 + x)
-6 + -1x + x2 = (-4(5 + x) + x(5 + x))
-6 + -1x + x2 = ((5 * -4 + x * -4) + x(5 + x))
-6 + -1x + x2 = ((-20 + -4x) + x(5 + x))
-6 + -1x + x2 = (-20 + -4x + (5 * x + x * x))
-6 + -1x + x2 = (-20 + -4x + (5x + x2))

Combine like terms: -4x + 5x = 1x
-6 + -1x + x2 = (-20 + 1x + x2)

Add '-1x2' to each side of the equation.
-6 + -1x + x2 + -1x2 = -20 + 1x + x2 + -1x2
