Simplifying (3x2 + 5x + -8) + (5x2 + -13x + -5) = 0 Reorder the terms: (-8 + 5x + 3x2) + (5x2 + -13x + -5) = 0 Remove parenthesis around (-8 + 5x + 3x2) -8 + 5x + 3x2 + (5x2 + -13x + -5) = 0 Reorder the terms: -8 + 5x + 3x2 + (-5 + -13x + 5x2) = 0 Remove parenthesis around (-5 + -13x + 5x2) -8 + 5x + 3x2 + -5 + -13x + 5x2 = 0 Reorder the terms: -8 + -5 + 5x + -13x + 3x2 + 5x2 = 0 Combine like terms: -8 + -5 = -13 -13 + 5x + -13x + 3x2 + 5x2 = 0 Combine like terms: 5x + -13x = -8x -13 + -8x + 3x2 + 5x2 = 0 Combine like terms: 3x2 + 5x2 = 8x2 -13 + -8x + 8x2 = 0 Solving -13 + -8x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -1.625 + -1x + x2 = 0 Move the constant term to the right: Add '1.625' to each side of the equation. -1.625 + -1x + 1.625 + x2 = 0 + 1.625 Reorder the terms: -1.625 + 1.625 + -1x + x2 = 0 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + -1x + x2 = 0 + 1.625 -1x + x2 = 0 + 1.625 Combine like terms: 0 + 1.625 = 1.625 -1x + x2 = 1.625 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 1.625 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 1.625 + 0.25 Combine like terms: 1.625 + 0.25 = 1.875 0.25 + -1x + x2 = 1.875 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 1.875 Calculate the square root of the right side: 1.369306394 Break this problem into two subproblems by setting (x + -0.5) equal to 1.369306394 and -1.369306394.Subproblem 1
x + -0.5 = 1.369306394 Simplifying x + -0.5 = 1.369306394 Reorder the terms: -0.5 + x = 1.369306394 Solving -0.5 + x = 1.369306394 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 1.369306394 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 1.369306394 + 0.5 x = 1.369306394 + 0.5 Combine like terms: 1.369306394 + 0.5 = 1.869306394 x = 1.869306394 Simplifying x = 1.869306394Subproblem 2
x + -0.5 = -1.369306394 Simplifying x + -0.5 = -1.369306394 Reorder the terms: -0.5 + x = -1.369306394 Solving -0.5 + x = -1.369306394 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -1.369306394 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -1.369306394 + 0.5 x = -1.369306394 + 0.5 Combine like terms: -1.369306394 + 0.5 = -0.869306394 x = -0.869306394 Simplifying x = -0.869306394Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.869306394, -0.869306394}
