Simplifying 2x2 + -3x = 66 Reorder the terms: -3x + 2x2 = 66 Solving -3x + 2x2 = 66 Solving for variable 'x'. Reorder the terms: -66 + -3x + 2x2 = 66 + -66 Combine like terms: 66 + -66 = 0 -66 + -3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -33 + -1.5x + x2 = 0 Move the constant term to the right: Add '33' to each side of the equation. -33 + -1.5x + 33 + x2 = 0 + 33 Reorder the terms: -33 + 33 + -1.5x + x2 = 0 + 33 Combine like terms: -33 + 33 = 0 0 + -1.5x + x2 = 0 + 33 -1.5x + x2 = 0 + 33 Combine like terms: 0 + 33 = 33 -1.5x + x2 = 33 The x term is -1.5x. 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. -1.5x + 0.5625 + x2 = 33 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 33 + 0.5625 Combine like terms: 33 + 0.5625 = 33.5625 0.5625 + -1.5x + x2 = 33.5625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 33.5625 Calculate the square root of the right side: 5.793315113 Break this problem into two subproblems by setting (x + -0.75) equal to 5.793315113 and -5.793315113.Subproblem 1
x + -0.75 = 5.793315113 Simplifying x + -0.75 = 5.793315113 Reorder the terms: -0.75 + x = 5.793315113 Solving -0.75 + x = 5.793315113 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 5.793315113 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 5.793315113 + 0.75 x = 5.793315113 + 0.75 Combine like terms: 5.793315113 + 0.75 = 6.543315113 x = 6.543315113 Simplifying x = 6.543315113Subproblem 2
x + -0.75 = -5.793315113 Simplifying x + -0.75 = -5.793315113 Reorder the terms: -0.75 + x = -5.793315113 Solving -0.75 + x = -5.793315113 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -5.793315113 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -5.793315113 + 0.75 x = -5.793315113 + 0.75 Combine like terms: -5.793315113 + 0.75 = -5.043315113 x = -5.043315113 Simplifying x = -5.043315113Solution
