Solution for (3z-4)(2-z)=0 equation:


Simplifying
(3z + -4)(2 + -1z) = 0

Reorder the terms:
(-4 + 3z)(2 + -1z) = 0

Multiply (-4 + 3z) * (2 + -1z)
(-4(2 + -1z) + 3z * (2 + -1z)) = 0
((2 * -4 + -1z * -4) + 3z * (2 + -1z)) = 0
((-8 + 4z) + 3z * (2 + -1z)) = 0
(-8 + 4z + (2 * 3z + -1z * 3z)) = 0
(-8 + 4z + (6z + -3z2)) = 0

Combine like terms: 4z + 6z = 10z
(-8 + 10z + -3z2) = 0

Solving
-8 + 10z + -3z2 = 0

Solving for variable 'z'.
