Solution for (2z-3)(8-z)=0 equation:


Simplifying
(2z + -3)(8 + -1z) = 0

Reorder the terms:
(-3 + 2z)(8 + -1z) = 0

Multiply (-3 + 2z) * (8 + -1z)
(-3(8 + -1z) + 2z * (8 + -1z)) = 0
((8 * -3 + -1z * -3) + 2z * (8 + -1z)) = 0
((-24 + 3z) + 2z * (8 + -1z)) = 0
(-24 + 3z + (8 * 2z + -1z * 2z)) = 0
(-24 + 3z + (16z + -2z2)) = 0

Combine like terms: 3z + 16z = 19z
(-24 + 19z + -2z2) = 0

Solving
-24 + 19z + -2z2 = 0
