Simplifying (7x2 + -9) + -1(8 + 3x) + -1(2x2 + -8x) = 0 Reorder the terms: (-9 + 7x2) + -1(8 + 3x) + -1(2x2 + -8x) = 0 Remove parenthesis around (-9 + 7x2) -9 + 7x2 + -1(8 + 3x) + -1(2x2 + -8x) = 0 -9 + 7x2 + (8 * -1 + 3x * -1) + -1(2x2 + -8x) = 0 -9 + 7x2 + (-8 + -3x) + -1(2x2 + -8x) = 0 Reorder the terms: -9 + 7x2 + -8 + -3x + -1(-8x + 2x2) = 0 -9 + 7x2 + -8 + -3x + (-8x * -1 + 2x2 * -1) = 0 -9 + 7x2 + -8 + -3x + (8x + -2x2) = 0 Reorder the terms: -9 + -8 + -3x + 8x + 7x2 + -2x2 = 0 Combine like terms: -9 + -8 = -17 -17 + -3x + 8x + 7x2 + -2x2 = 0 Combine like terms: -3x + 8x = 5x -17 + 5x + 7x2 + -2x2 = 0 Combine like terms: 7x2 + -2x2 = 5x2 -17 + 5x + 5x2 = 0 Solving -17 + 5x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -3.4 + x + x2 = 0 Move the constant term to the right: Add '3.4' to each side of the equation. -3.4 + x + 3.4 + x2 = 0 + 3.4 Reorder the terms: -3.4 + 3.4 + x + x2 = 0 + 3.4 Combine like terms: -3.4 + 3.4 = 0.0 0.0 + x + x2 = 0 + 3.4 x + x2 = 0 + 3.4 Combine like terms: 0 + 3.4 = 3.4 x + x2 = 3.4 The x term is x. 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. + 0.25 + x2 = 3.4 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 3.4 + 0.25 Combine like terms: 3.4 + 0.25 = 3.65 1.25 + x2 = 3.65 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 3.65 Calculate the square root of the right side: 1.910497317 Break this problem into two subproblems by setting (x + 0.5) equal to 1.910497317 and -1.910497317.Subproblem 1
x + 0.5 = 1.910497317 Simplifying x + 0.5 = 1.910497317 Reorder the terms: 0.5 + x = 1.910497317 Solving 0.5 + x = 1.910497317 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 = 1.910497317 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 1.910497317 + -0.5 x = 1.910497317 + -0.5 Combine like terms: 1.910497317 + -0.5 = 1.410497317 x = 1.410497317 Simplifying x = 1.410497317Subproblem 2
x + 0.5 = -1.910497317 Simplifying x + 0.5 = -1.910497317 Reorder the terms: 0.5 + x = -1.910497317 Solving 0.5 + x = -1.910497317 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 = -1.910497317 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -1.910497317 + -0.5 x = -1.910497317 + -0.5 Combine like terms: -1.910497317 + -0.5 = -2.410497317 x = -2.410497317 Simplifying x = -2.410497317Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.410497317, -2.410497317}
