Solution for (3z+1)(8+z)=0 equation:


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

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

Multiply (1 + 3z) * (8 + z)
(1(8 + z) + 3z * (8 + z)) = 0
((8 * 1 + z * 1) + 3z * (8 + z)) = 0
((8 + 1z) + 3z * (8 + z)) = 0
(8 + 1z + (8 * 3z + z * 3z)) = 0
(8 + 1z + (24z + 3z2)) = 0

Combine like terms: 1z + 24z = 25z
(8 + 25z + 3z2) = 0

Solving
8 + 25z + 3z2 = 0

Solving for variable 'z'.
