Ignore the factor 3.

Subproblem 1

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

Subproblem 2

Set the factor '(10 + -1s)' equal to zero and attempt to solve: Simplifying 10 + -1s = 0 Solving 10 + -1s = 0 Move all terms containing s to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + -1s = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -1s = 0 + -10 -1s = 0 + -10 Combine like terms: 0 + -10 = -10 -1s = -10 Divide each side by '-1'. s = 10 Simplifying s = 10

Solution

s = {-12, 10}
