(k + -3)(k + -1) = 24

Reorder the terms:
(-3 + k)(k + -1) = 24

Reorder the terms:
(-3 + k)(-1 + k) = 24

Multiply (-3 + k) * (-1 + k)
(-3(-1 + k) + k(-1 + k)) = 24
((-1 * -3 + k * -3) + k(-1 + k)) = 24
((3 + -3k) + k(-1 + k)) = 24
(3 + -3k + (-1 * k + k * k)) = 24
(3 + -3k + (-1k + k2)) = 24

Combine like terms: -3k + -1k = -4k
(3 + -4k + k2) = 24
