Simplifying 2y2 + 8y + -10 = -5 Reorder the terms: -10 + 8y + 2y2 = -5 Solving -10 + 8y + 2y2 = -5 Solving for variable 'y'. Reorder the terms: -10 + 5 + 8y + 2y2 = -5 + 5 Combine like terms: -10 + 5 = -5 -5 + 8y + 2y2 = -5 + 5 Combine like terms: -5 + 5 = 0 -5 + 8y + 2y2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -2.5 + 4y + y2 = 0 Move the constant term to the right: Add '2.5' to each side of the equation. -2.5 + 4y + 2.5 + y2 = 0 + 2.5 Reorder the terms: -2.5 + 2.5 + 4y + y2 = 0 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + 4y + y2 = 0 + 2.5 4y + y2 = 0 + 2.5 Combine like terms: 0 + 2.5 = 2.5 4y + y2 = 2.5 The y term is 4y. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4y + 4 + y2 = 2.5 + 4 Reorder the terms: 4 + 4y + y2 = 2.5 + 4 Combine like terms: 2.5 + 4 = 6.5 4 + 4y + y2 = 6.5 Factor a perfect square on the left side: (y + 2)(y + 2) = 6.5 Calculate the square root of the right side: 2.549509757 Break this problem into two subproblems by setting (y + 2) equal to 2.549509757 and -2.549509757.Subproblem 1
y + 2 = 2.549509757 Simplifying y + 2 = 2.549509757 Reorder the terms: 2 + y = 2.549509757 Solving 2 + y = 2.549509757 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + y = 2.549509757 + -2 Combine like terms: 2 + -2 = 0 0 + y = 2.549509757 + -2 y = 2.549509757 + -2 Combine like terms: 2.549509757 + -2 = 0.549509757 y = 0.549509757 Simplifying y = 0.549509757Subproblem 2
y + 2 = -2.549509757 Simplifying y + 2 = -2.549509757 Reorder the terms: 2 + y = -2.549509757 Solving 2 + y = -2.549509757 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + y = -2.549509757 + -2 Combine like terms: 2 + -2 = 0 0 + y = -2.549509757 + -2 y = -2.549509757 + -2 Combine like terms: -2.549509757 + -2 = -4.549509757 y = -4.549509757 Simplifying y = -4.549509757Solution
