Simplifying x2 + 31x + 13 = 0 Reorder the terms: 13 + 31x + x2 = 0 Solving 13 + 31x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-13' to each side of the equation. 13 + 31x + -13 + x2 = 0 + -13 Reorder the terms: 13 + -13 + 31x + x2 = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 31x + x2 = 0 + -13 31x + x2 = 0 + -13 Combine like terms: 0 + -13 = -13 31x + x2 = -13 The x term is 31x. Take half its coefficient (15.5). Square it (240.25) and add it to both sides. Add '240.25' to each side of the equation. 31x + 240.25 + x2 = -13 + 240.25 Reorder the terms: 240.25 + 31x + x2 = -13 + 240.25 Combine like terms: -13 + 240.25 = 227.25 240.25 + 31x + x2 = 227.25 Factor a perfect square on the left side: (x + 15.5)(x + 15.5) = 227.25 Calculate the square root of the right side: 15.074813432 Break this problem into two subproblems by setting (x + 15.5) equal to 15.074813432 and -15.074813432.Subproblem 1
x + 15.5 = 15.074813432 Simplifying x + 15.5 = 15.074813432 Reorder the terms: 15.5 + x = 15.074813432 Solving 15.5 + x = 15.074813432 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15.5' to each side of the equation. 15.5 + -15.5 + x = 15.074813432 + -15.5 Combine like terms: 15.5 + -15.5 = 0.0 0.0 + x = 15.074813432 + -15.5 x = 15.074813432 + -15.5 Combine like terms: 15.074813432 + -15.5 = -0.425186568 x = -0.425186568 Simplifying x = -0.425186568Subproblem 2
x + 15.5 = -15.074813432 Simplifying x + 15.5 = -15.074813432 Reorder the terms: 15.5 + x = -15.074813432 Solving 15.5 + x = -15.074813432 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-15.5' to each side of the equation. 15.5 + -15.5 + x = -15.074813432 + -15.5 Combine like terms: 15.5 + -15.5 = 0.0 0.0 + x = -15.074813432 + -15.5 x = -15.074813432 + -15.5 Combine like terms: -15.074813432 + -15.5 = -30.574813432 x = -30.574813432 Simplifying x = -30.574813432Solution
