Simplifying 2x2 + -45x + 180 = 0 Reorder the terms: 180 + -45x + 2x2 = 0 Solving 180 + -45x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 90 + -22.5x + x2 = 0 Move the constant term to the right: Add '-90' to each side of the equation. 90 + -22.5x + -90 + x2 = 0 + -90 Reorder the terms: 90 + -90 + -22.5x + x2 = 0 + -90 Combine like terms: 90 + -90 = 0 0 + -22.5x + x2 = 0 + -90 -22.5x + x2 = 0 + -90 Combine like terms: 0 + -90 = -90 -22.5x + x2 = -90 The x term is -22.5x. Take half its coefficient (-11.25). Square it (126.5625) and add it to both sides. Add '126.5625' to each side of the equation. -22.5x + 126.5625 + x2 = -90 + 126.5625 Reorder the terms: 126.5625 + -22.5x + x2 = -90 + 126.5625 Combine like terms: -90 + 126.5625 = 36.5625 126.5625 + -22.5x + x2 = 36.5625 Factor a perfect square on the left side: (x + -11.25)(x + -11.25) = 36.5625 Calculate the square root of the right side: 6.046693311 Break this problem into two subproblems by setting (x + -11.25) equal to 6.046693311 and -6.046693311.Subproblem 1
x + -11.25 = 6.046693311 Simplifying x + -11.25 = 6.046693311 Reorder the terms: -11.25 + x = 6.046693311 Solving -11.25 + x = 6.046693311 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11.25' to each side of the equation. -11.25 + 11.25 + x = 6.046693311 + 11.25 Combine like terms: -11.25 + 11.25 = 0.00 0.00 + x = 6.046693311 + 11.25 x = 6.046693311 + 11.25 Combine like terms: 6.046693311 + 11.25 = 17.296693311 x = 17.296693311 Simplifying x = 17.296693311Subproblem 2
x + -11.25 = -6.046693311 Simplifying x + -11.25 = -6.046693311 Reorder the terms: -11.25 + x = -6.046693311 Solving -11.25 + x = -6.046693311 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '11.25' to each side of the equation. -11.25 + 11.25 + x = -6.046693311 + 11.25 Combine like terms: -11.25 + 11.25 = 0.00 0.00 + x = -6.046693311 + 11.25 x = -6.046693311 + 11.25 Combine like terms: -6.046693311 + 11.25 = 5.203306689 x = 5.203306689 Simplifying x = 5.203306689Solution
