Simplifying 0 = y2 + -18y + -477 Reorder the terms: 0 = -477 + -18y + y2 Solving 0 = -477 + -18y + y2 Solving for variable 'y'. Combine like terms: 0 + 477 = 477 477 + 18y + -1y2 = -477 + -18y + y2 + 477 + 18y + -1y2 Reorder the terms: 477 + 18y + -1y2 = -477 + 477 + -18y + 18y + y2 + -1y2 Combine like terms: -477 + 477 = 0 477 + 18y + -1y2 = 0 + -18y + 18y + y2 + -1y2 477 + 18y + -1y2 = -18y + 18y + y2 + -1y2 Combine like terms: -18y + 18y = 0 477 + 18y + -1y2 = 0 + y2 + -1y2 477 + 18y + -1y2 = y2 + -1y2 Combine like terms: y2 + -1y2 = 0 477 + 18y + -1y2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -477 + -18y + y2 = 0 Move the constant term to the right: Add '477' to each side of the equation. -477 + -18y + 477 + y2 = 0 + 477 Reorder the terms: -477 + 477 + -18y + y2 = 0 + 477 Combine like terms: -477 + 477 = 0 0 + -18y + y2 = 0 + 477 -18y + y2 = 0 + 477 Combine like terms: 0 + 477 = 477 -18y + y2 = 477 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 = 477 + 81 Reorder the terms: 81 + -18y + y2 = 477 + 81 Combine like terms: 477 + 81 = 558 81 + -18y + y2 = 558 Factor a perfect square on the left side: (y + -9)(y + -9) = 558 Calculate the square root of the right side: 23.622023622 Break this problem into two subproblems by setting (y + -9) equal to 23.622023622 and -23.622023622.Subproblem 1
y + -9 = 23.622023622 Simplifying y + -9 = 23.622023622 Reorder the terms: -9 + y = 23.622023622 Solving -9 + y = 23.622023622 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 = 23.622023622 + 9 Combine like terms: -9 + 9 = 0 0 + y = 23.622023622 + 9 y = 23.622023622 + 9 Combine like terms: 23.622023622 + 9 = 32.622023622 y = 32.622023622 Simplifying y = 32.622023622Subproblem 2
y + -9 = -23.622023622 Simplifying y + -9 = -23.622023622 Reorder the terms: -9 + y = -23.622023622 Solving -9 + y = -23.622023622 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 = -23.622023622 + 9 Combine like terms: -9 + 9 = 0 0 + y = -23.622023622 + 9 y = -23.622023622 + 9 Combine like terms: -23.622023622 + 9 = -14.622023622 y = -14.622023622 Simplifying y = -14.622023622Solution
The solution to the problem is based on the solutions from the subproblems. y = {32.622023622, -14.622023622}
