Simplifying 2x2 + -5x + -72 = 0 Reorder the terms: -72 + -5x + 2x2 = 0 Solving -72 + -5x + 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'. -36 + -2.5x + x2 = 0 Move the constant term to the right: Add '36' to each side of the equation. -36 + -2.5x + 36 + x2 = 0 + 36 Reorder the terms: -36 + 36 + -2.5x + x2 = 0 + 36 Combine like terms: -36 + 36 = 0 0 + -2.5x + x2 = 0 + 36 -2.5x + x2 = 0 + 36 Combine like terms: 0 + 36 = 36 -2.5x + x2 = 36 The x term is -2.5x. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5x + 1.5625 + x2 = 36 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = 36 + 1.5625 Combine like terms: 36 + 1.5625 = 37.5625 1.5625 + -2.5x + x2 = 37.5625 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = 37.5625 Calculate the square root of the right side: 6.128825336 Break this problem into two subproblems by setting (x + -1.25) equal to 6.128825336 and -6.128825336.Subproblem 1
x + -1.25 = 6.128825336 Simplifying x + -1.25 = 6.128825336 Reorder the terms: -1.25 + x = 6.128825336 Solving -1.25 + x = 6.128825336 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + x = 6.128825336 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = 6.128825336 + 1.25 x = 6.128825336 + 1.25 Combine like terms: 6.128825336 + 1.25 = 7.378825336 x = 7.378825336 Simplifying x = 7.378825336Subproblem 2
x + -1.25 = -6.128825336 Simplifying x + -1.25 = -6.128825336 Reorder the terms: -1.25 + x = -6.128825336 Solving -1.25 + x = -6.128825336 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + x = -6.128825336 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = -6.128825336 + 1.25 x = -6.128825336 + 1.25 Combine like terms: -6.128825336 + 1.25 = -4.878825336 x = -4.878825336 Simplifying x = -4.878825336Solution
