Simplifying
(8 + z)(4z + 1) = 0

Reorder the terms:
(8 + z)(1 + 4z) = 0

Multiply (8 + z) * (1 + 4z)
(8(1 + 4z) + z(1 + 4z)) = 0
((1 * 8 + 4z * 8) + z(1 + 4z)) = 0
((8 + 32z) + z(1 + 4z)) = 0
(8 + 32z + (1 * z + 4z * z)) = 0
(8 + 32z + (1z + 4z2)) = 0

Combine like terms: 32z + 1z = 33z
(8 + 33z + 4z2) = 0
