Simplifying y2 + -6y + -13 = 0 Reorder the terms: -13 + -6y + y2 = 0 Solving -13 + -6y + y2 = 0 Solving for variable 'y'. Begin completing the square. Move the constant term to the right: Add '13' to each side of the equation. -13 + -6y + 13 + y2 = 0 + 13 Reorder the terms: -13 + 13 + -6y + y2 = 0 + 13 Combine like terms: -13 + 13 = 0 0 + -6y + y2 = 0 + 13 -6y + y2 = 0 + 13 Combine like terms: 0 + 13 = 13 -6y + y2 = 13 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 = 13 + 9 Reorder the terms: 9 + -6y + y2 = 13 + 9 Combine like terms: 13 + 9 = 22 9 + -6y + y2 = 22 Factor a perfect square on the left side: (y + -3)(y + -3) = 22 Calculate the square root of the right side: 4.69041576 Break this problem into two subproblems by setting (y + -3) equal to 4.69041576 and -4.69041576.Subproblem 1
y + -3 = 4.69041576 Simplifying y + -3 = 4.69041576 Reorder the terms: -3 + y = 4.69041576 Solving -3 + y = 4.69041576 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 = 4.69041576 + 3 Combine like terms: -3 + 3 = 0 0 + y = 4.69041576 + 3 y = 4.69041576 + 3 Combine like terms: 4.69041576 + 3 = 7.69041576 y = 7.69041576 Simplifying y = 7.69041576Subproblem 2
y + -3 = -4.69041576 Simplifying y + -3 = -4.69041576 Reorder the terms: -3 + y = -4.69041576 Solving -3 + y = -4.69041576 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 = -4.69041576 + 3 Combine like terms: -3 + 3 = 0 0 + y = -4.69041576 + 3 y = -4.69041576 + 3 Combine like terms: -4.69041576 + 3 = -1.69041576 y = -1.69041576 Simplifying y = -1.69041576Solution
The solution to the problem is based on the solutions from the subproblems. y = {7.69041576, -1.69041576}
