Simplifying 2y2 + -18y + -23 = 0 Reorder the terms: -23 + -18y + 2y2 = 0 Solving -23 + -18y + 2y2 = 0 Solving for variable 'y'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -11.5 + -9y + y2 = 0 Move the constant term to the right: Add '11.5' to each side of the equation. -11.5 + -9y + 11.5 + y2 = 0 + 11.5 Reorder the terms: -11.5 + 11.5 + -9y + y2 = 0 + 11.5 Combine like terms: -11.5 + 11.5 = 0.0 0.0 + -9y + y2 = 0 + 11.5 -9y + y2 = 0 + 11.5 Combine like terms: 0 + 11.5 = 11.5 -9y + y2 = 11.5 The y term is -9y. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9y + 20.25 + y2 = 11.5 + 20.25 Reorder the terms: 20.25 + -9y + y2 = 11.5 + 20.25 Combine like terms: 11.5 + 20.25 = 31.75 20.25 + -9y + y2 = 31.75 Factor a perfect square on the left side: (y + -4.5)(y + -4.5) = 31.75 Calculate the square root of the right side: 5.634713835 Break this problem into two subproblems by setting (y + -4.5) equal to 5.634713835 and -5.634713835.Subproblem 1
y + -4.5 = 5.634713835 Simplifying y + -4.5 = 5.634713835 Reorder the terms: -4.5 + y = 5.634713835 Solving -4.5 + y = 5.634713835 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + y = 5.634713835 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + y = 5.634713835 + 4.5 y = 5.634713835 + 4.5 Combine like terms: 5.634713835 + 4.5 = 10.134713835 y = 10.134713835 Simplifying y = 10.134713835Subproblem 2
y + -4.5 = -5.634713835 Simplifying y + -4.5 = -5.634713835 Reorder the terms: -4.5 + y = -5.634713835 Solving -4.5 + y = -5.634713835 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '4.5' to each side of the equation. -4.5 + 4.5 + y = -5.634713835 + 4.5 Combine like terms: -4.5 + 4.5 = 0.0 0.0 + y = -5.634713835 + 4.5 y = -5.634713835 + 4.5 Combine like terms: -5.634713835 + 4.5 = -1.134713835 y = -1.134713835 Simplifying y = -1.134713835Solution
