Simplifying x(2x + 13) + -33 = 0 Reorder the terms: x(13 + 2x) + -33 = 0 (13 * x + 2x * x) + -33 = 0 (13x + 2x2) + -33 = 0 Reorder the terms: -33 + 13x + 2x2 = 0 Solving -33 + 13x + 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'. -16.5 + 6.5x + x2 = 0 Move the constant term to the right: Add '16.5' to each side of the equation. -16.5 + 6.5x + 16.5 + x2 = 0 + 16.5 Reorder the terms: -16.5 + 16.5 + 6.5x + x2 = 0 + 16.5 Combine like terms: -16.5 + 16.5 = 0.0 0.0 + 6.5x + x2 = 0 + 16.5 6.5x + x2 = 0 + 16.5 Combine like terms: 0 + 16.5 = 16.5 6.5x + x2 = 16.5 The x term is 6.5x. Take half its coefficient (3.25). Square it (10.5625) and add it to both sides. Add '10.5625' to each side of the equation. 6.5x + 10.5625 + x2 = 16.5 + 10.5625 Reorder the terms: 10.5625 + 6.5x + x2 = 16.5 + 10.5625 Combine like terms: 16.5 + 10.5625 = 27.0625 10.5625 + 6.5x + x2 = 27.0625 Factor a perfect square on the left side: (x + 3.25)(x + 3.25) = 27.0625 Calculate the square root of the right side: 5.202163012 Break this problem into two subproblems by setting (x + 3.25) equal to 5.202163012 and -5.202163012.Subproblem 1
x + 3.25 = 5.202163012 Simplifying x + 3.25 = 5.202163012 Reorder the terms: 3.25 + x = 5.202163012 Solving 3.25 + x = 5.202163012 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = 5.202163012 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = 5.202163012 + -3.25 x = 5.202163012 + -3.25 Combine like terms: 5.202163012 + -3.25 = 1.952163012 x = 1.952163012 Simplifying x = 1.952163012Subproblem 2
x + 3.25 = -5.202163012 Simplifying x + 3.25 = -5.202163012 Reorder the terms: 3.25 + x = -5.202163012 Solving 3.25 + x = -5.202163012 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.25' to each side of the equation. 3.25 + -3.25 + x = -5.202163012 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = -5.202163012 + -3.25 x = -5.202163012 + -3.25 Combine like terms: -5.202163012 + -3.25 = -8.452163012 x = -8.452163012 Simplifying x = -8.452163012Solution
