Simplifying -1s2 = 4 + -4s Solving -1s2 = 4 + -4s Solving for variable 's'. Reorder the terms: -4 + 4s + -1s2 = 4 + -4s + -4 + 4s Reorder the terms: -4 + 4s + -1s2 = 4 + -4 + -4s + 4s Combine like terms: 4 + -4 = 0 -4 + 4s + -1s2 = 0 + -4s + 4s -4 + 4s + -1s2 = -4s + 4s Combine like terms: -4s + 4s = 0 -4 + 4s + -1s2 = 0 Factor a trinomial. (-2 + s)(2 + -1s) = 0Subproblem 1
Set the factor '(-2 + s)' equal to zero and attempt to solve: Simplifying -2 + s = 0 Solving -2 + s = 0 Move all terms containing s to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + s = 0 + 2 Combine like terms: -2 + 2 = 0 0 + s = 0 + 2 s = 0 + 2 Combine like terms: 0 + 2 = 2 s = 2 Simplifying s = 2Subproblem 2
Set the factor '(2 + -1s)' equal to zero and attempt to solve: Simplifying 2 + -1s = 0 Solving 2 + -1s = 0 Move all terms containing s to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1s = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1s = 0 + -2 -1s = 0 + -2 Combine like terms: 0 + -2 = -2 -1s = -2 Divide each side by '-1'. s = 2 Simplifying s = 2Solution
s = {2, 2}
