(5z-2)(3-z)=0

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

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

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

Multiply (-2 + 5z) * (3 + -1z)
(-2(3 + -1z) + 5z * (3 + -1z)) = 0
((3 * -2 + -1z * -2) + 5z * (3 + -1z)) = 0
((-6 + 2z) + 5z * (3 + -1z)) = 0
(-6 + 2z + (3 * 5z + -1z * 5z)) = 0
(-6 + 2z + (15z + -5z2)) = 0

Combine like terms: 2z + 15z = 17z
(-6 + 17z + -5z2) = 0

Solving
-6 + 17z + -5z2 = 0

Solving for variable 'z'.

Factor a trinomial.
