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


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

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

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

Combine like terms: 1z + 24z = 25z
(-8 + 25z + -3z2) = 0

Solving
-8 + 25z + -3z2 = 0

Solving for variable 'z'.
