Simplifying 4x2 + 31x + -33 = 0 Reorder the terms: -33 + 31x + 4x2 = 0 Solving -33 + 31x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -8.25 + 7.75x + x2 = 0 Move the constant term to the right: Add '8.25' to each side of the equation. -8.25 + 7.75x + 8.25 + x2 = 0 + 8.25 Reorder the terms: -8.25 + 8.25 + 7.75x + x2 = 0 + 8.25 Combine like terms: -8.25 + 8.25 = 0.00 0.00 + 7.75x + x2 = 0 + 8.25 7.75x + x2 = 0 + 8.25 Combine like terms: 0 + 8.25 = 8.25 7.75x + x2 = 8.25 The x term is 7.75x. Take half its coefficient (3.875). Square it (15.015625) and add it to both sides. Add '15.015625' to each side of the equation. 7.75x + 15.015625 + x2 = 8.25 + 15.015625 Reorder the terms: 15.015625 + 7.75x + x2 = 8.25 + 15.015625 Combine like terms: 8.25 + 15.015625 = 23.265625 15.015625 + 7.75x + x2 = 23.265625 Factor a perfect square on the left side: (x + 3.875)(x + 3.875) = 23.265625 Calculate the square root of the right side: 4.823445345 Break this problem into two subproblems by setting (x + 3.875) equal to 4.823445345 and -4.823445345.Subproblem 1
x + 3.875 = 4.823445345 Simplifying x + 3.875 = 4.823445345 Reorder the terms: 3.875 + x = 4.823445345 Solving 3.875 + x = 4.823445345 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.875' to each side of the equation. 3.875 + -3.875 + x = 4.823445345 + -3.875 Combine like terms: 3.875 + -3.875 = 0.000 0.000 + x = 4.823445345 + -3.875 x = 4.823445345 + -3.875 Combine like terms: 4.823445345 + -3.875 = 0.948445345 x = 0.948445345 Simplifying x = 0.948445345Subproblem 2
x + 3.875 = -4.823445345 Simplifying x + 3.875 = -4.823445345 Reorder the terms: 3.875 + x = -4.823445345 Solving 3.875 + x = -4.823445345 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.875' to each side of the equation. 3.875 + -3.875 + x = -4.823445345 + -3.875 Combine like terms: 3.875 + -3.875 = 0.000 0.000 + x = -4.823445345 + -3.875 x = -4.823445345 + -3.875 Combine like terms: -4.823445345 + -3.875 = -8.698445345 x = -8.698445345 Simplifying x = -8.698445345Solution
