Simplifying 8 + s(s + -1) = 18 Reorder the terms: 8 + s(-1 + s) = 18 8 + (-1 * s + s * s) = 18 8 + (-1s + s2) = 18 Solving 8 + -1s + s2 = 18 Solving for variable 's'. Reorder the terms: 8 + -18 + -1s + s2 = 18 + -18 Combine like terms: 8 + -18 = -10 -10 + -1s + s2 = 18 + -18 Combine like terms: 18 + -18 = 0 -10 + -1s + s2 = 0 Begin completing the square. Move the constant term to the right: Add '10' to each side of the equation. -10 + -1s + 10 + s2 = 0 + 10 Reorder the terms: -10 + 10 + -1s + s2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + -1s + s2 = 0 + 10 -1s + s2 = 0 + 10 Combine like terms: 0 + 10 = 10 -1s + s2 = 10 The s term is -1s. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1s + 0.25 + s2 = 10 + 0.25 Reorder the terms: 0.25 + -1s + s2 = 10 + 0.25 Combine like terms: 10 + 0.25 = 10.25 0.25 + -1s + s2 = 10.25 Factor a perfect square on the left side: (s + -0.5)(s + -0.5) = 10.25 Calculate the square root of the right side: 3.201562119 Break this problem into two subproblems by setting (s + -0.5) equal to 3.201562119 and -3.201562119.Subproblem 1
s + -0.5 = 3.201562119 Simplifying s + -0.5 = 3.201562119 Reorder the terms: -0.5 + s = 3.201562119 Solving -0.5 + s = 3.201562119 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + s = 3.201562119 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + s = 3.201562119 + 0.5 s = 3.201562119 + 0.5 Combine like terms: 3.201562119 + 0.5 = 3.701562119 s = 3.701562119 Simplifying s = 3.701562119Subproblem 2
s + -0.5 = -3.201562119 Simplifying s + -0.5 = -3.201562119 Reorder the terms: -0.5 + s = -3.201562119 Solving -0.5 + s = -3.201562119 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + s = -3.201562119 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + s = -3.201562119 + 0.5 s = -3.201562119 + 0.5 Combine like terms: -3.201562119 + 0.5 = -2.701562119 s = -2.701562119 Simplifying s = -2.701562119Solution
The solution to the problem is based on the solutions from the subproblems. s = {3.701562119, -2.701562119}
