Simplifying 2y2 + 11y + 11 = 0 Reorder the terms: 11 + 11y + 2y2 = 0 Solving 11 + 11y + 2y2 = 0 Solving for variable 'y'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 5.5 + 5.5y + y2 = 0 Move the constant term to the right: Add '-5.5' to each side of the equation. 5.5 + 5.5y + -5.5 + y2 = 0 + -5.5 Reorder the terms: 5.5 + -5.5 + 5.5y + y2 = 0 + -5.5 Combine like terms: 5.5 + -5.5 = 0.0 0.0 + 5.5y + y2 = 0 + -5.5 5.5y + y2 = 0 + -5.5 Combine like terms: 0 + -5.5 = -5.5 5.5y + y2 = -5.5 The y term is 5.5y. Take half its coefficient (2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. 5.5y + 7.5625 + y2 = -5.5 + 7.5625 Reorder the terms: 7.5625 + 5.5y + y2 = -5.5 + 7.5625 Combine like terms: -5.5 + 7.5625 = 2.0625 7.5625 + 5.5y + y2 = 2.0625 Factor a perfect square on the left side: (y + 2.75)(y + 2.75) = 2.0625 Calculate the square root of the right side: 1.436140662 Break this problem into two subproblems by setting (y + 2.75) equal to 1.436140662 and -1.436140662.Subproblem 1
y + 2.75 = 1.436140662 Simplifying y + 2.75 = 1.436140662 Reorder the terms: 2.75 + y = 1.436140662 Solving 2.75 + y = 1.436140662 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-2.75' to each side of the equation. 2.75 + -2.75 + y = 1.436140662 + -2.75 Combine like terms: 2.75 + -2.75 = 0.00 0.00 + y = 1.436140662 + -2.75 y = 1.436140662 + -2.75 Combine like terms: 1.436140662 + -2.75 = -1.313859338 y = -1.313859338 Simplifying y = -1.313859338Subproblem 2
y + 2.75 = -1.436140662 Simplifying y + 2.75 = -1.436140662 Reorder the terms: 2.75 + y = -1.436140662 Solving 2.75 + y = -1.436140662 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-2.75' to each side of the equation. 2.75 + -2.75 + y = -1.436140662 + -2.75 Combine like terms: 2.75 + -2.75 = 0.00 0.00 + y = -1.436140662 + -2.75 y = -1.436140662 + -2.75 Combine like terms: -1.436140662 + -2.75 = -4.186140662 y = -4.186140662 Simplifying y = -4.186140662Solution
