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


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

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

Multiply (3 + -1z) * (-2 + 3z)
(3(-2 + 3z) + -1z * (-2 + 3z)) = 0
((-2 * 3 + 3z * 3) + -1z * (-2 + 3z)) = 0
((-6 + 9z) + -1z * (-2 + 3z)) = 0
(-6 + 9z + (-2 * -1z + 3z * -1z)) = 0
(-6 + 9z + (2z + -3z2)) = 0

Combine like terms: 9z + 2z = 11z
(-6 + 11z + -3z2) = 0

Solving
-6 + 11z + -3z2 = 0

Solving for variable 'z'.

Factor a trinomial.
