Simplifying y2 + y + -24 = 0 Reorder the terms: -24 + y + y2 = 0 Solving -24 + y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '24' to each side of the equation. -24 + y + 24 + y2 = 0 + 24 Reorder the terms: -24 + 24 + y + y2 = 0 + 24 Combine like terms: -24 + 24 = 0 0 + y + y2 = 0 + 24 y + y2 = 0 + 24 Combine like terms: 0 + 24 = 24 y + y2 = 24 The y term is y. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. y + 0.25 + y2 = 24 + 0.25 Reorder the terms: 0.25 + y + y2 = 24 + 0.25 Combine like terms: 24 + 0.25 = 24.25 0.25 + y + y2 = 24.25 Factor a perfect square on the left side: (y + 0.5)(y + 0.5) = 24.25 Calculate the square root of the right side: 4.924428901 Break this problem into two subproblems by setting (y + 0.5) equal to 4.924428901 and -4.924428901.Subproblem 1
y + 0.5 = 4.924428901 Simplifying y + 0.5 = 4.924428901 Reorder the terms: 0.5 + y = 4.924428901 Solving 0.5 + y = 4.924428901 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + y = 4.924428901 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + y = 4.924428901 + -0.5 y = 4.924428901 + -0.5 Combine like terms: 4.924428901 + -0.5 = 4.424428901 y = 4.424428901 Simplifying y = 4.424428901Subproblem 2
y + 0.5 = -4.924428901 Simplifying y + 0.5 = -4.924428901 Reorder the terms: 0.5 + y = -4.924428901 Solving 0.5 + y = -4.924428901 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + y = -4.924428901 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + y = -4.924428901 + -0.5 y = -4.924428901 + -0.5 Combine like terms: -4.924428901 + -0.5 = -5.424428901 y = -5.424428901 Simplifying y = -5.424428901Solution
The solution to the problem is based on the solutions from the subproblems. y = {4.424428901, -5.424428901}
