-12 + 29z + 8z2 + -1(-3 + 8z)(-3 + z) = 0

Multiply (-3 + 8z) * (-3 + z)
-12 + 29z + 8z2 + -1(-3(-3 + z) + 8z * (-3 + z)) = 0
-12 + 29z + 8z2 + -1((-3 * -3 + z * -3) + 8z * (-3 + z)) = 0
-12 + 29z + 8z2 + -1((9 + -3z) + 8z * (-3 + z)) = 0
-12 + 29z + 8z2 + -1(9 + -3z + (-3 * 8z + z * 8z)) = 0
-12 + 29z + 8z2 + -1(9 + -3z + (-24z + 8z2)) = 0

Combine like terms: -3z + -24z = -27z
-12 + 29z + 8z2 + -1(9 + -27z + 8z2) = 0
-12 + 29z + 8z2 + (9 * -1 + -27z * -1 + 8z2 * -1) = 0
-12 + 29z + 8z2 + (-9 + 27z + -8z2) = 0

Reorder the terms:
-12 + -9 + 29z + 27z + 8z2 + -8z2 = 0

Combine like terms: -12 + -9 = -21
-21 + 29z + 27z + 8z2 + -8z2 = 0

Combine like terms: 29z + 27z = 56z
-21 + 56z + 8z2 + -8z2 = 0
