Simplifying 2x2 + 11x + -59 = 0 Reorder the terms: -59 + 11x + 2x2 = 0 Solving -59 + 11x + 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'. -29.5 + 5.5x + x2 = 0 Move the constant term to the right: Add '29.5' to each side of the equation. -29.5 + 5.5x + 29.5 + x2 = 0 + 29.5 Reorder the terms: -29.5 + 29.5 + 5.5x + x2 = 0 + 29.5 Combine like terms: -29.5 + 29.5 = 0.0 0.0 + 5.5x + x2 = 0 + 29.5 5.5x + x2 = 0 + 29.5 Combine like terms: 0 + 29.5 = 29.5 5.5x + x2 = 29.5 The x term is 5.5x. Take half its coefficient (2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. 5.5x + 7.5625 + x2 = 29.5 + 7.5625 Reorder the terms: 7.5625 + 5.5x + x2 = 29.5 + 7.5625 Combine like terms: 29.5 + 7.5625 = 37.0625 7.5625 + 5.5x + x2 = 37.0625 Factor a perfect square on the left side: (x + 2.75)(x + 2.75) = 37.0625 Calculate the square root of the right side: 6.087897831 Break this problem into two subproblems by setting (x + 2.75) equal to 6.087897831 and -6.087897831.Subproblem 1
x + 2.75 = 6.087897831 Simplifying x + 2.75 = 6.087897831 Reorder the terms: 2.75 + x = 6.087897831 Solving 2.75 + x = 6.087897831 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.75' to each side of the equation. 2.75 + -2.75 + x = 6.087897831 + -2.75 Combine like terms: 2.75 + -2.75 = 0.00 0.00 + x = 6.087897831 + -2.75 x = 6.087897831 + -2.75 Combine like terms: 6.087897831 + -2.75 = 3.337897831 x = 3.337897831 Simplifying x = 3.337897831Subproblem 2
x + 2.75 = -6.087897831 Simplifying x + 2.75 = -6.087897831 Reorder the terms: 2.75 + x = -6.087897831 Solving 2.75 + x = -6.087897831 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.75' to each side of the equation. 2.75 + -2.75 + x = -6.087897831 + -2.75 Combine like terms: 2.75 + -2.75 = 0.00 0.00 + x = -6.087897831 + -2.75 x = -6.087897831 + -2.75 Combine like terms: -6.087897831 + -2.75 = -8.837897831 x = -8.837897831 Simplifying x = -8.837897831Solution
