Simplifying
-4z(z + 6)(z + -8) = 0

Reorder the terms:
-4z(6 + z)(z + -8) = 0

Reorder the terms:
-4z(6 + z)(-8 + z) = 0

Multiply (6 + z) * (-8 + z)
-4z(6(-8 + z) + z(-8 + z)) = 0
-4z((-8 * 6 + z * 6) + z(-8 + z)) = 0
-4z((-48 + 6z) + z(-8 + z)) = 0
-4z(-48 + 6z + (-8 * z + z * z)) = 0
-4z(-48 + 6z + (-8z + z2)) = 0

Combine like terms: 6z + -8z = -2z
-4z(-48 + -2z + z2) = 0
(-48 * -4z + -2z * -4z + z2 * -4z) = 0
(192z + 8z2 + -4z3) = 0

Solving
192z + 8z2 + -4z3 = 0
