Simplifying (s + -4)(s + -4) + -81 = 0 Reorder the terms: (-4 + s)(s + -4) + -81 = 0 Reorder the terms: (-4 + s)(-4 + s) + -81 = 0 Multiply (-4 + s) * (-4 + s) (-4(-4 + s) + s(-4 + s)) + -81 = 0 ((-4 * -4 + s * -4) + s(-4 + s)) + -81 = 0 ((16 + -4s) + s(-4 + s)) + -81 = 0 (16 + -4s + (-4 * s + s * s)) + -81 = 0 (16 + -4s + (-4s + s2)) + -81 = 0 Combine like terms: -4s + -4s = -8s (16 + -8s + s2) + -81 = 0 Reorder the terms: 16 + -81 + -8s + s2 = 0 Combine like terms: 16 + -81 = -65 -65 + -8s + s2 = 0 Solving -65 + -8s + s2 = 0 Solving for variable 's'. Factor a trinomial. (-5 + -1s)(13 + -1s) = 0Subproblem 1
Set the factor '(-5 + -1s)' equal to zero and attempt to solve: Simplifying -5 + -1s = 0 Solving -5 + -1s = 0 Move all terms containing s to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + -1s = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -1s = 0 + 5 -1s = 0 + 5 Combine like terms: 0 + 5 = 5 -1s = 5 Divide each side by '-1'. s = -5 Simplifying s = -5Subproblem 2
Set the factor '(13 + -1s)' equal to zero and attempt to solve: Simplifying 13 + -1s = 0 Solving 13 + -1s = 0 Move all terms containing s to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + -1s = 0 + -13 Combine like terms: 13 + -13 = 0 0 + -1s = 0 + -13 -1s = 0 + -13 Combine like terms: 0 + -13 = -13 -1s = -13 Divide each side by '-1'. s = 13 Simplifying s = 13Solution
s = {-5, 13}
