Solution for z(4z-3)(z+3)=0 equation:


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

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

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

Multiply (-3 + 4z) * (3 + z)
z(-3(3 + z) + 4z * (3 + z)) = 0
z((3 * -3 + z * -3) + 4z * (3 + z)) = 0
z((-9 + -3z) + 4z * (3 + z)) = 0
z(-9 + -3z + (3 * 4z + z * 4z)) = 0
z(-9 + -3z + (12z + 4z2)) = 0

Combine like terms: -3z + 12z = 9z
z(-9 + 9z + 4z2) = 0
(-9 * z + 9z * z + 4z2 * z) = 0
(-9z + 9z2 + 4z3) = 0

Solving
-9z + 9z2 + 4z3 = 0

Solving for variable 'z'.

Factor out the Greatest Common Factor (GCF), 'z'.
