Simplifying y2 + 9y = -3 Reorder the terms: 9y + y2 = -3 Solving 9y + y2 = -3 Solving for variable 'y'. Reorder the terms: 3 + 9y + y2 = -3 + 3 Combine like terms: -3 + 3 = 0 3 + 9y + y2 = 0 Begin completing the square. Move the constant term to the right: Add '-3' to each side of the equation. 3 + 9y + -3 + y2 = 0 + -3 Reorder the terms: 3 + -3 + 9y + y2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 9y + y2 = 0 + -3 9y + y2 = 0 + -3 Combine like terms: 0 + -3 = -3 9y + y2 = -3 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 = -3 + 20.25 Reorder the terms: 20.25 + 9y + y2 = -3 + 20.25 Combine like terms: -3 + 20.25 = 17.25 20.25 + 9y + y2 = 17.25 Factor a perfect square on the left side: (y + 4.5)(y + 4.5) = 17.25 Calculate the square root of the right side: 4.153311931 Break this problem into two subproblems by setting (y + 4.5) equal to 4.153311931 and -4.153311931.Subproblem 1
y + 4.5 = 4.153311931 Simplifying y + 4.5 = 4.153311931 Reorder the terms: 4.5 + y = 4.153311931 Solving 4.5 + y = 4.153311931 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 = 4.153311931 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + y = 4.153311931 + -4.5 y = 4.153311931 + -4.5 Combine like terms: 4.153311931 + -4.5 = -0.346688069 y = -0.346688069 Simplifying y = -0.346688069Subproblem 2
y + 4.5 = -4.153311931 Simplifying y + 4.5 = -4.153311931 Reorder the terms: 4.5 + y = -4.153311931 Solving 4.5 + y = -4.153311931 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 = -4.153311931 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + y = -4.153311931 + -4.5 y = -4.153311931 + -4.5 Combine like terms: -4.153311931 + -4.5 = -8.653311931 y = -8.653311931 Simplifying y = -8.653311931Solution
