Simplifying s2 + 7s = 19 Reorder the terms: 7s + s2 = 19 Solving 7s + s2 = 19 Solving for variable 's'. Reorder the terms: -19 + 7s + s2 = 19 + -19 Combine like terms: 19 + -19 = 0 -19 + 7s + s2 = 0 Begin completing the square. Move the constant term to the right: Add '19' to each side of the equation. -19 + 7s + 19 + s2 = 0 + 19 Reorder the terms: -19 + 19 + 7s + s2 = 0 + 19 Combine like terms: -19 + 19 = 0 0 + 7s + s2 = 0 + 19 7s + s2 = 0 + 19 Combine like terms: 0 + 19 = 19 7s + s2 = 19 The s term is 7s. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7s + 12.25 + s2 = 19 + 12.25 Reorder the terms: 12.25 + 7s + s2 = 19 + 12.25 Combine like terms: 19 + 12.25 = 31.25 12.25 + 7s + s2 = 31.25 Factor a perfect square on the left side: (s + 3.5)(s + 3.5) = 31.25 Calculate the square root of the right side: 5.590169944 Break this problem into two subproblems by setting (s + 3.5) equal to 5.590169944 and -5.590169944.Subproblem 1
s + 3.5 = 5.590169944 Simplifying s + 3.5 = 5.590169944 Reorder the terms: 3.5 + s = 5.590169944 Solving 3.5 + s = 5.590169944 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + s = 5.590169944 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + s = 5.590169944 + -3.5 s = 5.590169944 + -3.5 Combine like terms: 5.590169944 + -3.5 = 2.090169944 s = 2.090169944 Simplifying s = 2.090169944Subproblem 2
s + 3.5 = -5.590169944 Simplifying s + 3.5 = -5.590169944 Reorder the terms: 3.5 + s = -5.590169944 Solving 3.5 + s = -5.590169944 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + s = -5.590169944 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + s = -5.590169944 + -3.5 s = -5.590169944 + -3.5 Combine like terms: -5.590169944 + -3.5 = -9.090169944 s = -9.090169944 Simplifying s = -9.090169944Solution
The solution to the problem is based on the solutions from the subproblems. s = {2.090169944, -9.090169944}
