Simplifying 2y2 + -11y + 8 = 0 Reorder the terms: 8 + -11y + 2y2 = 0 Solving 8 + -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'. 4 + -5.5y + y2 = 0 Move the constant term to the right: Add '-4' to each side of the equation. 4 + -5.5y + -4 + y2 = 0 + -4 Reorder the terms: 4 + -4 + -5.5y + y2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -5.5y + y2 = 0 + -4 -5.5y + y2 = 0 + -4 Combine like terms: 0 + -4 = -4 -5.5y + y2 = -4 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 = -4 + 7.5625 Reorder the terms: 7.5625 + -5.5y + y2 = -4 + 7.5625 Combine like terms: -4 + 7.5625 = 3.5625 7.5625 + -5.5y + y2 = 3.5625 Factor a perfect square on the left side: (y + -2.75)(y + -2.75) = 3.5625 Calculate the square root of the right side: 1.887458609 Break this problem into two subproblems by setting (y + -2.75) equal to 1.887458609 and -1.887458609.Subproblem 1
y + -2.75 = 1.887458609 Simplifying y + -2.75 = 1.887458609 Reorder the terms: -2.75 + y = 1.887458609 Solving -2.75 + y = 1.887458609 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 = 1.887458609 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + y = 1.887458609 + 2.75 y = 1.887458609 + 2.75 Combine like terms: 1.887458609 + 2.75 = 4.637458609 y = 4.637458609 Simplifying y = 4.637458609Subproblem 2
y + -2.75 = -1.887458609 Simplifying y + -2.75 = -1.887458609 Reorder the terms: -2.75 + y = -1.887458609 Solving -2.75 + y = -1.887458609 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 = -1.887458609 + 2.75 Combine like terms: -2.75 + 2.75 = 0.00 0.00 + y = -1.887458609 + 2.75 y = -1.887458609 + 2.75 Combine like terms: -1.887458609 + 2.75 = 0.862541391 y = 0.862541391 Simplifying y = 0.862541391Solution
