Solution for (3z+8)(1-z)=0 equation:


Simplifying
(3z + 8)(1 + -1z) = 0

Reorder the terms:
(8 + 3z)(1 + -1z) = 0

Multiply (8 + 3z) * (1 + -1z)
(8(1 + -1z) + 3z * (1 + -1z)) = 0
((1 * 8 + -1z * 8) + 3z * (1 + -1z)) = 0
((8 + -8z) + 3z * (1 + -1z)) = 0
(8 + -8z + (1 * 3z + -1z * 3z)) = 0
(8 + -8z + (3z + -3z2)) = 0

Combine like terms: -8z + 3z = -5z
(8 + -5z + -3z2) = 0

Solving
8 + -5z + -3z2 = 0
