Simplifying 3s = 2s2 + 1 Reorder the terms: 3s = 1 + 2s2 Solving 3s = 1 + 2s2 Solving for variable 's'. Reorder the terms: -1 + 3s + -2s2 = 1 + 2s2 + -1 + -2s2 Reorder the terms: -1 + 3s + -2s2 = 1 + -1 + 2s2 + -2s2 Combine like terms: 1 + -1 = 0 -1 + 3s + -2s2 = 0 + 2s2 + -2s2 -1 + 3s + -2s2 = 2s2 + -2s2 Combine like terms: 2s2 + -2s2 = 0 -1 + 3s + -2s2 = 0 Factor a trinomial. (-1 + s)(1 + -2s) = 0Subproblem 1
Set the factor '(-1 + s)' equal to zero and attempt to solve: Simplifying -1 + s = 0 Solving -1 + s = 0 Move all terms containing s to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + s = 0 + 1 Combine like terms: -1 + 1 = 0 0 + s = 0 + 1 s = 0 + 1 Combine like terms: 0 + 1 = 1 s = 1 Simplifying s = 1Subproblem 2
Set the factor '(1 + -2s)' equal to zero and attempt to solve: Simplifying 1 + -2s = 0 Solving 1 + -2s = 0 Move all terms containing s to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -2s = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2s = 0 + -1 -2s = 0 + -1 Combine like terms: 0 + -1 = -1 -2s = -1 Divide each side by '-2'. s = 0.5 Simplifying s = 0.5Solution
s = {1, 0.5}
