Simplifying s2 + 10s + 3 = 0 Reorder the terms: 3 + 10s + s2 = 0 Solving 3 + 10s + s2 = 0 Solving for variable 's'. Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + 10s + -3 + s2 = 0 + -3 Reorder the terms: 3 + -3 + 10s + s2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 10s + s2 = 0 + -3 10s + s2 = 0 + -3 Combine like terms: 0 + -3 = -3 10s + s2 = -3 The s term is 10s. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10s + 25 + s2 = -3 + 25 Reorder the terms: 25 + 10s + s2 = -3 + 25 Combine like terms: -3 + 25 = 22 25 + 10s + s2 = 22 Factor a perfect square on the left side: (s + 5)(s + 5) = 22 Calculate the square root of the right side: 4.69041576 Break this problem into two subproblems by setting (s + 5) equal to 4.69041576 and -4.69041576.Subproblem 1
s + 5 = 4.69041576 Simplifying s + 5 = 4.69041576 Reorder the terms: 5 + s = 4.69041576 Solving 5 + s = 4.69041576 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + s = 4.69041576 + -5 Combine like terms: 5 + -5 = 0 0 + s = 4.69041576 + -5 s = 4.69041576 + -5 Combine like terms: 4.69041576 + -5 = -0.30958424 s = -0.30958424 Simplifying s = -0.30958424Subproblem 2
s + 5 = -4.69041576 Simplifying s + 5 = -4.69041576 Reorder the terms: 5 + s = -4.69041576 Solving 5 + s = -4.69041576 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + s = -4.69041576 + -5 Combine like terms: 5 + -5 = 0 0 + s = -4.69041576 + -5 s = -4.69041576 + -5 Combine like terms: -4.69041576 + -5 = -9.69041576 s = -9.69041576 Simplifying s = -9.69041576Solution
The solution to the problem is based on the solutions from the subproblems. s = {-0.30958424, -9.69041576}
