Simplifying (4y2 + 5y + -2) + -1(9y + 3) = 0 Reorder the terms: (-2 + 5y + 4y2) + -1(9y + 3) = 0 Remove parenthesis around (-2 + 5y + 4y2) -2 + 5y + 4y2 + -1(9y + 3) = 0 Reorder the terms: -2 + 5y + 4y2 + -1(3 + 9y) = 0 -2 + 5y + 4y2 + (3 * -1 + 9y * -1) = 0 -2 + 5y + 4y2 + (-3 + -9y) = 0 Reorder the terms: -2 + -3 + 5y + -9y + 4y2 = 0 Combine like terms: -2 + -3 = -5 -5 + 5y + -9y + 4y2 = 0 Combine like terms: 5y + -9y = -4y -5 + -4y + 4y2 = 0 Solving -5 + -4y + 4y2 = 0 Solving for variable 'y'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -1.25 + -1y + y2 = 0 Move the constant term to the right: Add '1.25' to each side of the equation. -1.25 + -1y + 1.25 + y2 = 0 + 1.25 Reorder the terms: -1.25 + 1.25 + -1y + y2 = 0 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + -1y + y2 = 0 + 1.25 -1y + y2 = 0 + 1.25 Combine like terms: 0 + 1.25 = 1.25 -1y + y2 = 1.25 The y term is -1y. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1y + 0.25 + y2 = 1.25 + 0.25 Reorder the terms: 0.25 + -1y + y2 = 1.25 + 0.25 Combine like terms: 1.25 + 0.25 = 1.5 0.25 + -1y + y2 = 1.5 Factor a perfect square on the left side: (y + -0.5)(y + -0.5) = 1.5 Calculate the square root of the right side: 1.224744871 Break this problem into two subproblems by setting (y + -0.5) equal to 1.224744871 and -1.224744871.Subproblem 1
y + -0.5 = 1.224744871 Simplifying y + -0.5 = 1.224744871 Reorder the terms: -0.5 + y = 1.224744871 Solving -0.5 + y = 1.224744871 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + y = 1.224744871 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + y = 1.224744871 + 0.5 y = 1.224744871 + 0.5 Combine like terms: 1.224744871 + 0.5 = 1.724744871 y = 1.724744871 Simplifying y = 1.724744871Subproblem 2
y + -0.5 = -1.224744871 Simplifying y + -0.5 = -1.224744871 Reorder the terms: -0.5 + y = -1.224744871 Solving -0.5 + y = -1.224744871 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + y = -1.224744871 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + y = -1.224744871 + 0.5 y = -1.224744871 + 0.5 Combine like terms: -1.224744871 + 0.5 = -0.724744871 y = -0.724744871 Simplifying y = -0.724744871Solution
