Simplifying s2 + 5s = -1 Reorder the terms: 5s + s2 = -1 Solving 5s + s2 = -1 Solving for variable 's'. Reorder the terms: 1 + 5s + s2 = -1 + 1 Combine like terms: -1 + 1 = 0 1 + 5s + s2 = 0 Begin completing the square. Move the constant term to the right: Add '-1' to each side of the equation. 1 + 5s + -1 + s2 = 0 + -1 Reorder the terms: 1 + -1 + 5s + s2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 5s + s2 = 0 + -1 5s + s2 = 0 + -1 Combine like terms: 0 + -1 = -1 5s + s2 = -1 The s term is 5s. Take half its coefficient (2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. 5s + 6.25 + s2 = -1 + 6.25 Reorder the terms: 6.25 + 5s + s2 = -1 + 6.25 Combine like terms: -1 + 6.25 = 5.25 6.25 + 5s + s2 = 5.25 Factor a perfect square on the left side: (s + 2.5)(s + 2.5) = 5.25 Calculate the square root of the right side: 2.291287847 Break this problem into two subproblems by setting (s + 2.5) equal to 2.291287847 and -2.291287847.Subproblem 1
s + 2.5 = 2.291287847 Simplifying s + 2.5 = 2.291287847 Reorder the terms: 2.5 + s = 2.291287847 Solving 2.5 + s = 2.291287847 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + s = 2.291287847 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + s = 2.291287847 + -2.5 s = 2.291287847 + -2.5 Combine like terms: 2.291287847 + -2.5 = -0.208712153 s = -0.208712153 Simplifying s = -0.208712153Subproblem 2
s + 2.5 = -2.291287847 Simplifying s + 2.5 = -2.291287847 Reorder the terms: 2.5 + s = -2.291287847 Solving 2.5 + s = -2.291287847 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-2.5' to each side of the equation. 2.5 + -2.5 + s = -2.291287847 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + s = -2.291287847 + -2.5 s = -2.291287847 + -2.5 Combine like terms: -2.291287847 + -2.5 = -4.791287847 s = -4.791287847 Simplifying s = -4.791287847Solution
The solution to the problem is based on the solutions from the subproblems. s = {-0.208712153, -4.791287847}
