(6-z)(3z+8)=0

Solution for (6-z)(3z+8)=0 equation:

Simplifying
(6 + -1z)(3z + 8) = 0

Reorder the terms:
(6 + -1z)(8 + 3z) = 0

Multiply (6 + -1z) * (8 + 3z)
(6(8 + 3z) + -1z * (8 + 3z)) = 0
((8 * 6 + 3z * 6) + -1z * (8 + 3z)) = 0
((48 + 18z) + -1z * (8 + 3z)) = 0
(48 + 18z + (8 * -1z + 3z * -1z)) = 0
(48 + 18z + (-8z + -3z2)) = 0

Combine like terms: 18z + -8z = 10z
(48 + 10z + -3z2) = 0

Solving
48 + 10z + -3z2 = 0

Solving for variable 'z'.
