Solution for (2z+8)*(3z-6)=0 equation:


Simplifying
(2z + 8)(3z + -6) = 0

Reorder the terms:
(8 + 2z)(3z + -6) = 0

Reorder the terms:
(8 + 2z)(-6 + 3z) = 0

Multiply (8 + 2z) * (-6 + 3z)
(8(-6 + 3z) + 2z * (-6 + 3z)) = 0
((-6 * 8 + 3z * 8) + 2z * (-6 + 3z)) = 0
((-48 + 24z) + 2z * (-6 + 3z)) = 0
(-48 + 24z + (-6 * 2z + 3z * 2z)) = 0
(-48 + 24z + (-12z + 6z2)) = 0

Combine like terms: 24z + -12z = 12z
(-48 + 12z + 6z2) = 0

Solving
-48 + 12z + 6z2 = 0
