Simplifying y2 + -6y + -56 = 0 Reorder the terms: -56 + -6y + y2 = 0 Solving -56 + -6y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '56' to each side of the equation. -56 + -6y + 56 + y2 = 0 + 56 Reorder the terms: -56 + 56 + -6y + y2 = 0 + 56 Combine like terms: -56 + 56 = 0 0 + -6y + y2 = 0 + 56 -6y + y2 = 0 + 56 Combine like terms: 0 + 56 = 56 -6y + y2 = 56 The y term is -6y. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6y + 9 + y2 = 56 + 9 Reorder the terms: 9 + -6y + y2 = 56 + 9 Combine like terms: 56 + 9 = 65 9 + -6y + y2 = 65 Factor a perfect square on the left side: (y + -3)(y + -3) = 65 Calculate the square root of the right side: 8.062257748 Break this problem into two subproblems by setting (y + -3) equal to 8.062257748 and -8.062257748.Subproblem 1
y + -3 = 8.062257748 Simplifying y + -3 = 8.062257748 Reorder the terms: -3 + y = 8.062257748 Solving -3 + y = 8.062257748 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + y = 8.062257748 + 3 Combine like terms: -3 + 3 = 0 0 + y = 8.062257748 + 3 y = 8.062257748 + 3 Combine like terms: 8.062257748 + 3 = 11.062257748 y = 11.062257748 Simplifying y = 11.062257748Subproblem 2
y + -3 = -8.062257748 Simplifying y + -3 = -8.062257748 Reorder the terms: -3 + y = -8.062257748 Solving -3 + y = -8.062257748 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + y = -8.062257748 + 3 Combine like terms: -3 + 3 = 0 0 + y = -8.062257748 + 3 y = -8.062257748 + 3 Combine like terms: -8.062257748 + 3 = -5.062257748 y = -5.062257748 Simplifying y = -5.062257748Solution
