Simplifying 2x2 + 13x + 15 = 2 Reorder the terms: 15 + 13x + 2x2 = 2 Solving 15 + 13x + 2x2 = 2 Solving for variable 'x'. Reorder the terms: 15 + -2 + 13x + 2x2 = 2 + -2 Combine like terms: 15 + -2 = 13 13 + 13x + 2x2 = 2 + -2 Combine like terms: 2 + -2 = 0 13 + 13x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 6.5 + 6.5x + x2 = 0 Move the constant term to the right: Add '-6.5' to each side of the equation. 6.5 + 6.5x + -6.5 + x2 = 0 + -6.5 Reorder the terms: 6.5 + -6.5 + 6.5x + x2 = 0 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + 6.5x + x2 = 0 + -6.5 6.5x + x2 = 0 + -6.5 Combine like terms: 0 + -6.5 = -6.5 6.5x + x2 = -6.5 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 = -6.5 + 10.5625 Reorder the terms: 10.5625 + 6.5x + x2 = -6.5 + 10.5625 Combine like terms: -6.5 + 10.5625 = 4.0625 10.5625 + 6.5x + x2 = 4.0625 Factor a perfect square on the left side: (x + 3.25)(x + 3.25) = 4.0625 Calculate the square root of the right side: 2.015564437 Break this problem into two subproblems by setting (x + 3.25) equal to 2.015564437 and -2.015564437.Subproblem 1
x + 3.25 = 2.015564437 Simplifying x + 3.25 = 2.015564437 Reorder the terms: 3.25 + x = 2.015564437 Solving 3.25 + x = 2.015564437 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 = 2.015564437 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = 2.015564437 + -3.25 x = 2.015564437 + -3.25 Combine like terms: 2.015564437 + -3.25 = -1.234435563 x = -1.234435563 Simplifying x = -1.234435563Subproblem 2
x + 3.25 = -2.015564437 Simplifying x + 3.25 = -2.015564437 Reorder the terms: 3.25 + x = -2.015564437 Solving 3.25 + x = -2.015564437 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 = -2.015564437 + -3.25 Combine like terms: 3.25 + -3.25 = 0.00 0.00 + x = -2.015564437 + -3.25 x = -2.015564437 + -3.25 Combine like terms: -2.015564437 + -3.25 = -5.265564437 x = -5.265564437 Simplifying x = -5.265564437Solution
