(6-z)(5z-3)=0

Solution for (6-z)(5z-3)=0 equation:

Simplifying
(6 + -1z)(5z + -3) = 0

Reorder the terms:
(6 + -1z)(-3 + 5z) = 0

Multiply (6 + -1z) * (-3 + 5z)
(6(-3 + 5z) + -1z * (-3 + 5z)) = 0
((-3 * 6 + 5z * 6) + -1z * (-3 + 5z)) = 0
((-18 + 30z) + -1z * (-3 + 5z)) = 0
(-18 + 30z + (-3 * -1z + 5z * -1z)) = 0
(-18 + 30z + (3z + -5z2)) = 0

Combine like terms: 30z + 3z = 33z
(-18 + 33z + -5z2) = 0

Solving
-18 + 33z + -5z2 = 0

Solving for variable 'z'.
