Simplifying 4s2 + 24s + -11 = 0 Reorder the terms: -11 + 24s + 4s2 = 0 Solving -11 + 24s + 4s2 = 0 Solving for variable 's'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -2.75 + 6s + s2 = 0 Move the constant term to the right: Add '2.75' to each side of the equation. -2.75 + 6s + 2.75 + s2 = 0 + 2.75 Reorder the terms: -2.75 + 2.75 + 6s + s2 = 0 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + 6s + s2 = 0 + 2.75 6s + s2 = 0 + 2.75 Combine like terms: 0 + 2.75 = 2.75 6s + s2 = 2.75 The s term is 6s. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6s + 9 + s2 = 2.75 + 9 Reorder the terms: 9 + 6s + s2 = 2.75 + 9 Combine like terms: 2.75 + 9 = 11.75 9 + 6s + s2 = 11.75 Factor a perfect square on the left side: (s + 3)(s + 3) = 11.75 Calculate the square root of the right side: 3.4278273 Break this problem into two subproblems by setting (s + 3) equal to 3.4278273 and -3.4278273.Subproblem 1
s + 3 = 3.4278273 Simplifying s + 3 = 3.4278273 Reorder the terms: 3 + s = 3.4278273 Solving 3 + s = 3.4278273 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + s = 3.4278273 + -3 Combine like terms: 3 + -3 = 0 0 + s = 3.4278273 + -3 s = 3.4278273 + -3 Combine like terms: 3.4278273 + -3 = 0.4278273 s = 0.4278273 Simplifying s = 0.4278273Subproblem 2
s + 3 = -3.4278273 Simplifying s + 3 = -3.4278273 Reorder the terms: 3 + s = -3.4278273 Solving 3 + s = -3.4278273 Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + s = -3.4278273 + -3 Combine like terms: 3 + -3 = 0 0 + s = -3.4278273 + -3 s = -3.4278273 + -3 Combine like terms: -3.4278273 + -3 = -6.4278273 s = -6.4278273 Simplifying s = -6.4278273Solution
The solution to the problem is based on the solutions from the subproblems. s = {0.4278273, -6.4278273}
