Simplifying (x2 + 2x + -5) + (3x2 + -1x + 4) = 0 Reorder the terms: (-5 + 2x + x2) + (3x2 + -1x + 4) = 0 Remove parenthesis around (-5 + 2x + x2) -5 + 2x + x2 + (3x2 + -1x + 4) = 0 Reorder the terms: -5 + 2x + x2 + (4 + -1x + 3x2) = 0 Remove parenthesis around (4 + -1x + 3x2) -5 + 2x + x2 + 4 + -1x + 3x2 = 0 Reorder the terms: -5 + 4 + 2x + -1x + x2 + 3x2 = 0 Combine like terms: -5 + 4 = -1 -1 + 2x + -1x + x2 + 3x2 = 0 Combine like terms: 2x + -1x = 1x -1 + 1x + x2 + 3x2 = 0 Combine like terms: x2 + 3x2 = 4x2 -1 + 1x + 4x2 = 0 Solving -1 + 1x + 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'. -0.25 + 0.25x + x2 = 0 Move the constant term to the right: Add '0.25' to each side of the equation. -0.25 + 0.25x + 0.25 + x2 = 0 + 0.25 Reorder the terms: -0.25 + 0.25 + 0.25x + x2 = 0 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + 0.25x + x2 = 0 + 0.25 0.25x + x2 = 0 + 0.25 Combine like terms: 0 + 0.25 = 0.25 0.25x + x2 = 0.25 The x term is 0.25x. Take half its coefficient (0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. 0.25x + 0.015625 + x2 = 0.25 + 0.015625 Reorder the terms: 0.015625 + 0.25x + x2 = 0.25 + 0.015625 Combine like terms: 0.25 + 0.015625 = 0.265625 0.015625 + 0.25x + x2 = 0.265625 Factor a perfect square on the left side: (x + 0.125)(x + 0.125) = 0.265625 Calculate the square root of the right side: 0.515388203 Break this problem into two subproblems by setting (x + 0.125) equal to 0.515388203 and -0.515388203.Subproblem 1
x + 0.125 = 0.515388203 Simplifying x + 0.125 = 0.515388203 Reorder the terms: 0.125 + x = 0.515388203 Solving 0.125 + x = 0.515388203 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.125' to each side of the equation. 0.125 + -0.125 + x = 0.515388203 + -0.125 Combine like terms: 0.125 + -0.125 = 0.000 0.000 + x = 0.515388203 + -0.125 x = 0.515388203 + -0.125 Combine like terms: 0.515388203 + -0.125 = 0.390388203 x = 0.390388203 Simplifying x = 0.390388203Subproblem 2
x + 0.125 = -0.515388203 Simplifying x + 0.125 = -0.515388203 Reorder the terms: 0.125 + x = -0.515388203 Solving 0.125 + x = -0.515388203 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.125' to each side of the equation. 0.125 + -0.125 + x = -0.515388203 + -0.125 Combine like terms: 0.125 + -0.125 = 0.000 0.000 + x = -0.515388203 + -0.125 x = -0.515388203 + -0.125 Combine like terms: -0.515388203 + -0.125 = -0.640388203 x = -0.640388203 Simplifying x = -0.640388203Solution
