Simplifying 2y2 + 5y = 20.50 Reorder the terms: 5y + 2y2 = 20.50 Solving 5y + 2y2 = 20.50 Solving for variable 'y'. Reorder the terms: -20.50 + 5y + 2y2 = 20.50 + -20.50 Combine like terms: 20.50 + -20.50 = 0.00 -20.50 + 5y + 2y2 = 0.00 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -10.25 + 2.5y + y2 = 0.00 Move the constant term to the right: Add '10.25' to each side of the equation. -10.25 + 2.5y + 10.25 + y2 = 0.00 + 10.25 Reorder the terms: -10.25 + 10.25 + 2.5y + y2 = 0.00 + 10.25 Combine like terms: -10.25 + 10.25 = 0.00 0.00 + 2.5y + y2 = 0.00 + 10.25 2.5y + y2 = 0.00 + 10.25 Combine like terms: 0.00 + 10.25 = 10.25 2.5y + y2 = 10.25 The y term is 2.5y. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5y + 1.5625 + y2 = 10.25 + 1.5625 Reorder the terms: 1.5625 + 2.5y + y2 = 10.25 + 1.5625 Combine like terms: 10.25 + 1.5625 = 11.8125 1.5625 + 2.5y + y2 = 11.8125 Factor a perfect square on the left side: (y + 1.25)(y + 1.25) = 11.8125 Calculate the square root of the right side: 3.436931771 Break this problem into two subproblems by setting (y + 1.25) equal to 3.436931771 and -3.436931771.Subproblem 1
y + 1.25 = 3.436931771 Simplifying y + 1.25 = 3.436931771 Reorder the terms: 1.25 + y = 3.436931771 Solving 1.25 + y = 3.436931771 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + y = 3.436931771 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + y = 3.436931771 + -1.25 y = 3.436931771 + -1.25 Combine like terms: 3.436931771 + -1.25 = 2.186931771 y = 2.186931771 Simplifying y = 2.186931771Subproblem 2
y + 1.25 = -3.436931771 Simplifying y + 1.25 = -3.436931771 Reorder the terms: 1.25 + y = -3.436931771 Solving 1.25 + y = -3.436931771 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-1.25' to each side of the equation. 1.25 + -1.25 + y = -3.436931771 + -1.25 Combine like terms: 1.25 + -1.25 = 0.00 0.00 + y = -3.436931771 + -1.25 y = -3.436931771 + -1.25 Combine like terms: -3.436931771 + -1.25 = -4.686931771 y = -4.686931771 Simplifying y = -4.686931771Solution
