Simplifying 2y2 + -9y + -19 = 0 Reorder the terms: -19 + -9y + 2y2 = 0 Solving -19 + -9y + 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'. -9.5 + -4.5y + y2 = 0 Move the constant term to the right: Add '9.5' to each side of the equation. -9.5 + -4.5y + 9.5 + y2 = 0 + 9.5 Reorder the terms: -9.5 + 9.5 + -4.5y + y2 = 0 + 9.5 Combine like terms: -9.5 + 9.5 = 0.0 0.0 + -4.5y + y2 = 0 + 9.5 -4.5y + y2 = 0 + 9.5 Combine like terms: 0 + 9.5 = 9.5 -4.5y + y2 = 9.5 The y term is -4.5y. Take half its coefficient (-2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. -4.5y + 5.0625 + y2 = 9.5 + 5.0625 Reorder the terms: 5.0625 + -4.5y + y2 = 9.5 + 5.0625 Combine like terms: 9.5 + 5.0625 = 14.5625 5.0625 + -4.5y + y2 = 14.5625 Factor a perfect square on the left side: (y + -2.25)(y + -2.25) = 14.5625 Calculate the square root of the right side: 3.816084381 Break this problem into two subproblems by setting (y + -2.25) equal to 3.816084381 and -3.816084381.Subproblem 1
y + -2.25 = 3.816084381 Simplifying y + -2.25 = 3.816084381 Reorder the terms: -2.25 + y = 3.816084381 Solving -2.25 + y = 3.816084381 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + y = 3.816084381 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + y = 3.816084381 + 2.25 y = 3.816084381 + 2.25 Combine like terms: 3.816084381 + 2.25 = 6.066084381 y = 6.066084381 Simplifying y = 6.066084381Subproblem 2
y + -2.25 = -3.816084381 Simplifying y + -2.25 = -3.816084381 Reorder the terms: -2.25 + y = -3.816084381 Solving -2.25 + y = -3.816084381 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '2.25' to each side of the equation. -2.25 + 2.25 + y = -3.816084381 + 2.25 Combine like terms: -2.25 + 2.25 = 0.00 0.00 + y = -3.816084381 + 2.25 y = -3.816084381 + 2.25 Combine like terms: -3.816084381 + 2.25 = -1.566084381 y = -1.566084381 Simplifying y = -1.566084381Solution
