Simplifying 5s2 + -4s + -4 = 0 Reorder the terms: -4 + -4s + 5s2 = 0 Solving -4 + -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'. -0.8 + -0.8s + s2 = 0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + -0.8s + 0.8 + s2 = 0 + 0.8 Reorder the terms: -0.8 + 0.8 + -0.8s + s2 = 0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + -0.8s + s2 = 0 + 0.8 -0.8s + s2 = 0 + 0.8 Combine like terms: 0 + 0.8 = 0.8 -0.8s + s2 = 0.8 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 = 0.8 + 0.16 Reorder the terms: 0.16 + -0.8s + s2 = 0.8 + 0.16 Combine like terms: 0.8 + 0.16 = 0.96 0.16 + -0.8s + s2 = 0.96 Factor a perfect square on the left side: (s + -0.4)(s + -0.4) = 0.96 Calculate the square root of the right side: 0.979795897 Break this problem into two subproblems by setting (s + -0.4) equal to 0.979795897 and -0.979795897.Subproblem 1
s + -0.4 = 0.979795897 Simplifying s + -0.4 = 0.979795897 Reorder the terms: -0.4 + s = 0.979795897 Solving -0.4 + s = 0.979795897 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 = 0.979795897 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + s = 0.979795897 + 0.4 s = 0.979795897 + 0.4 Combine like terms: 0.979795897 + 0.4 = 1.379795897 s = 1.379795897 Simplifying s = 1.379795897Subproblem 2
s + -0.4 = -0.979795897 Simplifying s + -0.4 = -0.979795897 Reorder the terms: -0.4 + s = -0.979795897 Solving -0.4 + s = -0.979795897 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 = -0.979795897 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + s = -0.979795897 + 0.4 s = -0.979795897 + 0.4 Combine like terms: -0.979795897 + 0.4 = -0.579795897 s = -0.579795897 Simplifying s = -0.579795897Solution
The solution to the problem is based on the solutions from the subproblems. s = {1.379795897, -0.579795897}
