Simplifying y2 + 18y + 28 = 0 Reorder the terms: 28 + 18y + y2 = 0 Solving 28 + 18y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '-28' to each side of the equation. 28 + 18y + -28 + y2 = 0 + -28 Reorder the terms: 28 + -28 + 18y + y2 = 0 + -28 Combine like terms: 28 + -28 = 0 0 + 18y + y2 = 0 + -28 18y + y2 = 0 + -28 Combine like terms: 0 + -28 = -28 18y + y2 = -28 The y term is 18y. Take half its coefficient (9). Square it (81) and add it to both sides. Add '81' to each side of the equation. 18y + 81 + y2 = -28 + 81 Reorder the terms: 81 + 18y + y2 = -28 + 81 Combine like terms: -28 + 81 = 53 81 + 18y + y2 = 53 Factor a perfect square on the left side: (y + 9)(y + 9) = 53 Calculate the square root of the right side: 7.280109889 Break this problem into two subproblems by setting (y + 9) equal to 7.280109889 and -7.280109889.Subproblem 1
y + 9 = 7.280109889 Simplifying y + 9 = 7.280109889 Reorder the terms: 9 + y = 7.280109889 Solving 9 + y = 7.280109889 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + y = 7.280109889 + -9 Combine like terms: 9 + -9 = 0 0 + y = 7.280109889 + -9 y = 7.280109889 + -9 Combine like terms: 7.280109889 + -9 = -1.719890111 y = -1.719890111 Simplifying y = -1.719890111Subproblem 2
y + 9 = -7.280109889 Simplifying y + 9 = -7.280109889 Reorder the terms: 9 + y = -7.280109889 Solving 9 + y = -7.280109889 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + y = -7.280109889 + -9 Combine like terms: 9 + -9 = 0 0 + y = -7.280109889 + -9 y = -7.280109889 + -9 Combine like terms: -7.280109889 + -9 = -16.280109889 y = -16.280109889 Simplifying y = -16.280109889Solution
The solution to the problem is based on the solutions from the subproblems. y = {-1.719890111, -16.280109889}
