Simplifying 4s(s + 1) = -1 Reorder the terms: 4s(1 + s) = -1 (1 * 4s + s * 4s) = -1 (4s + 4s2) = -1 Solving 4s + 4s2 = -1 Solving for variable 's'. Reorder the terms: 1 + 4s + 4s2 = -1 + 1 Combine like terms: -1 + 1 = 0 1 + 4s + 4s2 = 0 Factor a trinomial. (1 + 2s)(1 + 2s) = 0Subproblem 1
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 = -0.5Subproblem 2
