Simplifying (3x2 + -5x + 6) + (9 + -8x + -4x2) = 0 Reorder the terms: (6 + -5x + 3x2) + (9 + -8x + -4x2) = 0 Remove parenthesis around (6 + -5x + 3x2) 6 + -5x + 3x2 + (9 + -8x + -4x2) = 0 Remove parenthesis around (9 + -8x + -4x2) 6 + -5x + 3x2 + 9 + -8x + -4x2 = 0 Reorder the terms: 6 + 9 + -5x + -8x + 3x2 + -4x2 = 0 Combine like terms: 6 + 9 = 15 15 + -5x + -8x + 3x2 + -4x2 = 0 Combine like terms: -5x + -8x = -13x 15 + -13x + 3x2 + -4x2 = 0 Combine like terms: 3x2 + -4x2 = -1x2 15 + -13x + -1x2 = 0 Solving 15 + -13x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -15 + 13x + x2 = 0 Move the constant term to the right: Add '15' to each side of the equation. -15 + 13x + 15 + x2 = 0 + 15 Reorder the terms: -15 + 15 + 13x + x2 = 0 + 15 Combine like terms: -15 + 15 = 0 0 + 13x + x2 = 0 + 15 13x + x2 = 0 + 15 Combine like terms: 0 + 15 = 15 13x + x2 = 15 The x term is 13x. Take half its coefficient (6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. 13x + 42.25 + x2 = 15 + 42.25 Reorder the terms: 42.25 + 13x + x2 = 15 + 42.25 Combine like terms: 15 + 42.25 = 57.25 42.25 + 13x + x2 = 57.25 Factor a perfect square on the left side: (x + 6.5)(x + 6.5) = 57.25 Calculate the square root of the right side: 7.566372975 Break this problem into two subproblems by setting (x + 6.5) equal to 7.566372975 and -7.566372975.Subproblem 1
x + 6.5 = 7.566372975 Simplifying x + 6.5 = 7.566372975 Reorder the terms: 6.5 + x = 7.566372975 Solving 6.5 + x = 7.566372975 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = 7.566372975 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = 7.566372975 + -6.5 x = 7.566372975 + -6.5 Combine like terms: 7.566372975 + -6.5 = 1.066372975 x = 1.066372975 Simplifying x = 1.066372975Subproblem 2
x + 6.5 = -7.566372975 Simplifying x + 6.5 = -7.566372975 Reorder the terms: 6.5 + x = -7.566372975 Solving 6.5 + x = -7.566372975 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = -7.566372975 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = -7.566372975 + -6.5 x = -7.566372975 + -6.5 Combine like terms: -7.566372975 + -6.5 = -14.066372975 x = -14.066372975 Simplifying x = -14.066372975Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.066372975, -14.066372975}
