Simplifying s2 + -3s = 11 Reorder the terms: -3s + s2 = 11 Solving -3s + s2 = 11 Solving for variable 's'. Reorder the terms: -11 + -3s + s2 = 11 + -11 Combine like terms: 11 + -11 = 0 -11 + -3s + s2 = 0 Begin completing the square. Move the constant term to the right: Add '11' to each side of the equation. -11 + -3s + 11 + s2 = 0 + 11 Reorder the terms: -11 + 11 + -3s + s2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -3s + s2 = 0 + 11 -3s + s2 = 0 + 11 Combine like terms: 0 + 11 = 11 -3s + s2 = 11 The s term is -3s. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3s + 2.25 + s2 = 11 + 2.25 Reorder the terms: 2.25 + -3s + s2 = 11 + 2.25 Combine like terms: 11 + 2.25 = 13.25 2.25 + -3s + s2 = 13.25 Factor a perfect square on the left side: (s + -1.5)(s + -1.5) = 13.25 Calculate the square root of the right side: 3.640054945 Break this problem into two subproblems by setting (s + -1.5) equal to 3.640054945 and -3.640054945.Subproblem 1
s + -1.5 = 3.640054945 Simplifying s + -1.5 = 3.640054945 Reorder the terms: -1.5 + s = 3.640054945 Solving -1.5 + s = 3.640054945 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + s = 3.640054945 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + s = 3.640054945 + 1.5 s = 3.640054945 + 1.5 Combine like terms: 3.640054945 + 1.5 = 5.140054945 s = 5.140054945 Simplifying s = 5.140054945Subproblem 2
s + -1.5 = -3.640054945 Simplifying s + -1.5 = -3.640054945 Reorder the terms: -1.5 + s = -3.640054945 Solving -1.5 + s = -3.640054945 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + s = -3.640054945 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + s = -3.640054945 + 1.5 s = -3.640054945 + 1.5 Combine like terms: -3.640054945 + 1.5 = -2.140054945 s = -2.140054945 Simplifying s = -2.140054945Solution
The solution to the problem is based on the solutions from the subproblems. s = {5.140054945, -2.140054945}
