Solution for (3z-2)(z+4)= equation:


Simplifying
(3z + -2)(z + 4) = 0

Reorder the terms:
(-2 + 3z)(z + 4) = 0

Reorder the terms:
(-2 + 3z)(4 + z) = 0

Multiply (-2 + 3z) * (4 + z)
(-2(4 + z) + 3z * (4 + z)) = 0
((4 * -2 + z * -2) + 3z * (4 + z)) = 0
((-8 + -2z) + 3z * (4 + z)) = 0
(-8 + -2z + (4 * 3z + z * 3z)) = 0
(-8 + -2z + (12z + 3z2)) = 0

Combine like terms: -2z + 12z = 10z
(-8 + 10z + 3z2) = 0

Solving
-8 + 10z + 3z2 = 0

Solving for variable 'z'.
