Simplifying 4s2 + 12s + -9 = 0 Reorder the terms: -9 + 12s + 4s2 = 0 Solving -9 + 12s + 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'. -2.25 + 3s + s2 = 0 Move the constant term to the right: Add '2.25' to each side of the equation. -2.25 + 3s + 2.25 + s2 = 0 + 2.25 Reorder the terms: -2.25 + 2.25 + 3s + s2 = 0 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + 3s + s2 = 0 + 2.25 3s + s2 = 0 + 2.25 Combine like terms: 0 + 2.25 = 2.25 3s + s2 = 2.25 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 = 2.25 + 2.25 Reorder the terms: 2.25 + 3s + s2 = 2.25 + 2.25 Combine like terms: 2.25 + 2.25 = 4.5 2.25 + 3s + s2 = 4.5 Factor a perfect square on the left side: (s + 1.5)(s + 1.5) = 4.5 Calculate the square root of the right side: 2.121320344 Break this problem into two subproblems by setting (s + 1.5) equal to 2.121320344 and -2.121320344.Subproblem 1
s + 1.5 = 2.121320344 Simplifying s + 1.5 = 2.121320344 Reorder the terms: 1.5 + s = 2.121320344 Solving 1.5 + s = 2.121320344 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 = 2.121320344 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + s = 2.121320344 + -1.5 s = 2.121320344 + -1.5 Combine like terms: 2.121320344 + -1.5 = 0.621320344 s = 0.621320344 Simplifying s = 0.621320344Subproblem 2
s + 1.5 = -2.121320344 Simplifying s + 1.5 = -2.121320344 Reorder the terms: 1.5 + s = -2.121320344 Solving 1.5 + s = -2.121320344 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 = -2.121320344 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + s = -2.121320344 + -1.5 s = -2.121320344 + -1.5 Combine like terms: -2.121320344 + -1.5 = -3.621320344 s = -3.621320344 Simplifying s = -3.621320344Solution
The solution to the problem is based on the solutions from the subproblems. s = {0.621320344, -3.621320344}
