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

Solution for (6-z)(4z+3)=0 equation:

Simplifying
(6 + -1z)(4z + 3) = 0

Reorder the terms:
(6 + -1z)(3 + 4z) = 0

Multiply (6 + -1z) * (3 + 4z)
(6(3 + 4z) + -1z * (3 + 4z)) = 0
((3 * 6 + 4z * 6) + -1z * (3 + 4z)) = 0
((18 + 24z) + -1z * (3 + 4z)) = 0
(18 + 24z + (3 * -1z + 4z * -1z)) = 0
(18 + 24z + (-3z + -4z2)) = 0

Combine like terms: 24z + -3z = 21z
(18 + 21z + -4z2) = 0

Solving
18 + 21z + -4z2 = 0

Solving for variable 'z'.
