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


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

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

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

Combine like terms: 4z + -3z = 1z
(-6 + 1z + 2z2) = 0

Solving
-6 + 1z + 2z2 = 0

Solving for variable 'z'.

Factor a trinomial.
