Simplifying 2y2 + 17y + 20 = 0 Reorder the terms: 20 + 17y + 2y2 = 0 Solving 20 + 17y + 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'. 10 + 8.5y + y2 = 0 Move the constant term to the right: Add '-10' to each side of the equation. 10 + 8.5y + -10 + y2 = 0 + -10 Reorder the terms: 10 + -10 + 8.5y + y2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + 8.5y + y2 = 0 + -10 8.5y + y2 = 0 + -10 Combine like terms: 0 + -10 = -10 8.5y + y2 = -10 The y term is 8.5y. Take half its coefficient (4.25). Square it (18.0625) and add it to both sides. Add '18.0625' to each side of the equation. 8.5y + 18.0625 + y2 = -10 + 18.0625 Reorder the terms: 18.0625 + 8.5y + y2 = -10 + 18.0625 Combine like terms: -10 + 18.0625 = 8.0625 18.0625 + 8.5y + y2 = 8.0625 Factor a perfect square on the left side: (y + 4.25)(y + 4.25) = 8.0625 Calculate the square root of the right side: 2.839454173 Break this problem into two subproblems by setting (y + 4.25) equal to 2.839454173 and -2.839454173.Subproblem 1
y + 4.25 = 2.839454173 Simplifying y + 4.25 = 2.839454173 Reorder the terms: 4.25 + y = 2.839454173 Solving 4.25 + y = 2.839454173 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + y = 2.839454173 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + y = 2.839454173 + -4.25 y = 2.839454173 + -4.25 Combine like terms: 2.839454173 + -4.25 = -1.410545827 y = -1.410545827 Simplifying y = -1.410545827Subproblem 2
y + 4.25 = -2.839454173 Simplifying y + 4.25 = -2.839454173 Reorder the terms: 4.25 + y = -2.839454173 Solving 4.25 + y = -2.839454173 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-4.25' to each side of the equation. 4.25 + -4.25 + y = -2.839454173 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + y = -2.839454173 + -4.25 y = -2.839454173 + -4.25 Combine like terms: -2.839454173 + -4.25 = -7.089454173 y = -7.089454173 Simplifying y = -7.089454173Solution
