Solution for (3z-2)(9+z)=0 equation:


Simplifying
(3z + -2)(9 + z) = 0

Reorder the terms:
(-2 + 3z)(9 + z) = 0

Multiply (-2 + 3z) * (9 + z)
(-2(9 + z) + 3z * (9 + z)) = 0
((9 * -2 + z * -2) + 3z * (9 + z)) = 0
((-18 + -2z) + 3z * (9 + z)) = 0
(-18 + -2z + (9 * 3z + z * 3z)) = 0
(-18 + -2z + (27z + 3z2)) = 0

Combine like terms: -2z + 27z = 25z
(-18 + 25z + 3z2) = 0
