Solution for (2+z)(3z-8)=0 equation: 


Simplifying
(2 + z)(3z + -8) = 0

Reorder the terms:
(2 + z)(-8 + 3z) = 0

Multiply (2 + z) * (-8 + 3z)
(2(-8 + 3z) + z(-8 + 3z)) = 0
((-8 * 2 + 3z * 2) + z(-8 + 3z)) = 0
((-16 + 6z) + z(-8 + 3z)) = 0
(-16 + 6z + (-8 * z + 3z * z)) = 0
(-16 + 6z + (-8z + 3z2)) = 0
