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

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

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

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

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

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

Combine like terms: 3z + 8z = 11z
-2z(24 + 11z + z2) = 0
(24 * -2z + 11z * -2z + z2 * -2z) = 0
(-48z + -22z2 + -2z3) = 0

Solving
-48z + -22z2 + -2z3 = 0

Solving for variable 'z'.

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

Subproblem 3
Set the factor '(3 + z)' equal to zero and attempt to solve:

Simplifying
3 + z = 0

Solving
3 + z = 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 + z = 0 + -3

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

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

Simplifying
z = -3
Solution
z = {0, -8, -3}
