Simplifying y2 + -9y + 3 = 0 Reorder the terms: 3 + -9y + y2 = 0 Solving 3 + -9y + y2 = 0 Solving for variable 'y'. 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 = 8.653311931 y = 8.653311931 Simplifying y = 8.653311931Subproblem 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 = 0.346688069 y = 0.346688069 Simplifying y = 0.346688069Solution
