Simplifying 2y2 + -3y + -7 = 0 Reorder the terms: -7 + -3y + 2y2 = 0 Solving -7 + -3y + 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'. -3.5 + -1.5y + y2 = 0 Move the constant term to the right: Add '3.5' to each side of the equation. -3.5 + -1.5y + 3.5 + y2 = 0 + 3.5 Reorder the terms: -3.5 + 3.5 + -1.5y + y2 = 0 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + -1.5y + y2 = 0 + 3.5 -1.5y + y2 = 0 + 3.5 Combine like terms: 0 + 3.5 = 3.5 -1.5y + y2 = 3.5 The y term is -1.5y. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5y + 0.5625 + y2 = 3.5 + 0.5625 Reorder the terms: 0.5625 + -1.5y + y2 = 3.5 + 0.5625 Combine like terms: 3.5 + 0.5625 = 4.0625 0.5625 + -1.5y + y2 = 4.0625 Factor a perfect square on the left side: (y + -0.75)(y + -0.75) = 4.0625 Calculate the square root of the right side: 2.015564437 Break this problem into two subproblems by setting (y + -0.75) equal to 2.015564437 and -2.015564437.Subproblem 1
y + -0.75 = 2.015564437 Simplifying y + -0.75 = 2.015564437 Reorder the terms: -0.75 + y = 2.015564437 Solving -0.75 + y = 2.015564437 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + y = 2.015564437 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + y = 2.015564437 + 0.75 y = 2.015564437 + 0.75 Combine like terms: 2.015564437 + 0.75 = 2.765564437 y = 2.765564437 Simplifying y = 2.765564437Subproblem 2
y + -0.75 = -2.015564437 Simplifying y + -0.75 = -2.015564437 Reorder the terms: -0.75 + y = -2.015564437 Solving -0.75 + y = -2.015564437 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + y = -2.015564437 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + y = -2.015564437 + 0.75 y = -2.015564437 + 0.75 Combine like terms: -2.015564437 + 0.75 = -1.265564437 y = -1.265564437 Simplifying y = -1.265564437Solution
