Simplifying 5s2 + 4s + -2 = 0 Reorder the terms: -2 + 4s + 5s2 = 0 Solving -2 + 4s + 5s2 = 0 Solving for variable 's'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -0.4 + 0.8s + s2 = 0 Move the constant term to the right: Add '0.4' to each side of the equation. -0.4 + 0.8s + 0.4 + s2 = 0 + 0.4 Reorder the terms: -0.4 + 0.4 + 0.8s + s2 = 0 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + 0.8s + s2 = 0 + 0.4 0.8s + s2 = 0 + 0.4 Combine like terms: 0 + 0.4 = 0.4 0.8s + s2 = 0.4 The s term is 0.8s. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8s + 0.16 + s2 = 0.4 + 0.16 Reorder the terms: 0.16 + 0.8s + s2 = 0.4 + 0.16 Combine like terms: 0.4 + 0.16 = 0.56 0.16 + 0.8s + s2 = 0.56 Factor a perfect square on the left side: (s + 0.4)(s + 0.4) = 0.56 Calculate the square root of the right side: 0.748331477 Break this problem into two subproblems by setting (s + 0.4) equal to 0.748331477 and -0.748331477.Subproblem 1
s + 0.4 = 0.748331477 Simplifying s + 0.4 = 0.748331477 Reorder the terms: 0.4 + s = 0.748331477 Solving 0.4 + s = 0.748331477 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + s = 0.748331477 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + s = 0.748331477 + -0.4 s = 0.748331477 + -0.4 Combine like terms: 0.748331477 + -0.4 = 0.348331477 s = 0.348331477 Simplifying s = 0.348331477Subproblem 2
s + 0.4 = -0.748331477 Simplifying s + 0.4 = -0.748331477 Reorder the terms: 0.4 + s = -0.748331477 Solving 0.4 + s = -0.748331477 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + s = -0.748331477 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + s = -0.748331477 + -0.4 s = -0.748331477 + -0.4 Combine like terms: -0.748331477 + -0.4 = -1.148331477 s = -1.148331477 Simplifying s = -1.148331477Solution
The solution to the problem is based on the solutions from the subproblems. s = {0.348331477, -1.148331477}
