Multiply (3 + 2z) * (-3 + z)
-9 + 9z + z2 = (3(-3 + z) + 2z * (-3 + z))
-9 + 9z + z2 = ((-3 * 3 + z * 3) + 2z * (-3 + z))
-9 + 9z + z2 = ((-9 + 3z) + 2z * (-3 + z))
-9 + 9z + z2 = (-9 + 3z + (-3 * 2z + z * 2z))
-9 + 9z + z2 = (-9 + 3z + (-6z + 2z2))

Combine like terms: 3z + -6z = -3z
-9 + 9z + z2 = (-9 + -3z + 2z2)

Add '9' to each side of the equation.
-9 + 9z + 9 + z2 = -9 + -3z + 9 + 2z2

-9 + 9 + 9z + z2 = -9 + -3z + 9 + 2z2

Combine like terms: -9 + 9 = 0
0 + 9z + z2 = -9 + -3z + 9 + 2z2
9z + z2 = -9 + -3z + 9 + 2z2

Reorder the terms:
9z + z2 = -9 + 9 + -3z + 2z2

Combine like terms: -9 + 9 = 0
9z + z2 = 0 + -3z + 2z2
9z + z2 = -3z + 2z2

Solving
9z + z2 = -3z + 2z2

Solving for variable 'z'.

Reorder the terms:
9z + 3z + z2 + -2z2 = -3z + 2z2 + 3z + -2z2

Combine like terms: 9z + 3z = 12z
12z + z2 + -2z2 = -3z + 2z2 + 3z + -2z2

Combine like terms: z2 + -2z2 = -1z2
12z + -1z2 = -3z + 2z2 + 3z + -2z2

Reorder the terms:
12z + -1z2 = -3z + 3z + 2z2 + -2z2

Combine like terms: -3z + 3z = 0
12z + -1z2 = 0 + 2z2 + -2z2
12z + -1z2 = 2z2 + -2z2

Combine like terms: 2z2 + -2z2 = 0
12z + -1z2 = 0

Factor out the Greatest Common Factor (GCF), 'z'.
z(12 + -1z) = 0

Subproblem 1

Set the factor 'z' equal to zero and attempt to solve: Simplifying z = 0 Solving z = 0 Move all terms containing z to the left, all other terms to the right. Simplifying z = 0

Subproblem 2

Set the factor '(12 + -1z)' equal to zero and attempt to solve: Simplifying 12 + -1z = 0 Solving 12 + -1z = 0 Move all terms containing z to the left, all other terms to the right. Add '-12' to each side of the equation. 12 + -12 + -1z = 0 + -12 Combine like terms: 12 + -12 = 0 0 + -1z = 0 + -12 -1z = 0 + -12 Combine like terms: 0 + -12 = -12 -1z = -12 Divide each side by '-1'. z = 12 Simplifying z = 12

Solution

z = {0, 12}
