Solution for (3z-2)(5-z)=0 equation:


Simplifying
(3z + -2)(5 + -1z) = 0

Reorder the terms:
(-2 + 3z)(5 + -1z) = 0

Multiply (-2 + 3z) * (5 + -1z)
(-2(5 + -1z) + 3z * (5 + -1z)) = 0
((5 * -2 + -1z * -2) + 3z * (5 + -1z)) = 0
((-10 + 2z) + 3z * (5 + -1z)) = 0
(-10 + 2z + (5 * 3z + -1z * 3z)) = 0
(-10 + 2z + (15z + -3z2)) = 0

Combine like terms: 2z + 15z = 17z
(-10 + 17z + -3z2) = 0
