(8+z)(4z+6)=0

Solution for (8+z)(4z+6)=0 equation:

Simplifying
(8 + z)(4z + 6) = 0

Reorder the terms:
(8 + z)(6 + 4z) = 0

Multiply (8 + z) * (6 + 4z)
(8(6 + 4z) + z(6 + 4z)) = 0
((6 * 8 + 4z * 8) + z(6 + 4z)) = 0
((48 + 32z) + z(6 + 4z)) = 0
(48 + 32z + (6 * z + 4z * z)) = 0
(48 + 32z + (6z + 4z2)) = 0

Combine like terms: 32z + 6z = 38z
(48 + 38z + 4z2) = 0

Solving
48 + 38z + 4z2 = 0

Solving for variable 'z'.

Factor out the Greatest Common Factor (GCF), '2'.

Subproblem 1
Set the factor '(8 + z)' equal to zero and attempt to solve:

Simplifying
8 + z = 0

Solving
8 + z = 0

Move all terms containing z to the left, all other terms to the right.

Add '-8' to each side of the equation.
8 + -8 + z = 0 + -8

Combine like terms: 8 + -8 = 0
0 + z = 0 + -8
z = 0 + -8

Combine like terms: 0 + -8 = -8
z = -8

Simplifying
z = -8
Subproblem 2
Set the factor '(3 + 2z)' equal to zero and attempt to solve:

Simplifying
3 + 2z = 0

Solving
3 + 2z = 0

Move all terms containing z to the left, all other terms to the right.

Add '-3' to each side of the equation.
3 + -3 + 2z = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 2z = 0 + -3
2z = 0 + -3

Combine like terms: 0 + -3 = -3
2z = -3

Divide each side by '2'.
z = -1.5

Simplifying
z = -1.5
Solution
z = {-8, -1.5}
