Simplifying (-2x + 2) + -1(x2 + x + -9) = 0 Reorder the terms: (2 + -2x) + -1(x2 + x + -9) = 0 Remove parenthesis around (2 + -2x) 2 + -2x + -1(x2 + x + -9) = 0 Reorder the terms: 2 + -2x + -1(-9 + x + x2) = 0 2 + -2x + (-9 * -1 + x * -1 + x2 * -1) = 0 2 + -2x + (9 + -1x + -1x2) = 0 Reorder the terms: 2 + 9 + -2x + -1x + -1x2 = 0 Combine like terms: 2 + 9 = 11 11 + -2x + -1x + -1x2 = 0 Combine like terms: -2x + -1x = -3x 11 + -3x + -1x2 = 0 Solving 11 + -3x + -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'. -11 + 3x + x2 = 0 Move the constant term to the right: Add '11' to each side of the equation. -11 + 3x + 11 + x2 = 0 + 11 Reorder the terms: -11 + 11 + 3x + x2 = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 3x + x2 = 0 + 11 3x + x2 = 0 + 11 Combine like terms: 0 + 11 = 11 3x + x2 = 11 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 11 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 11 + 2.25 Combine like terms: 11 + 2.25 = 13.25 2.25 + 3x + x2 = 13.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 13.25 Calculate the square root of the right side: 3.640054945 Break this problem into two subproblems by setting (x + 1.5) equal to 3.640054945 and -3.640054945.Subproblem 1
x + 1.5 = 3.640054945 Simplifying x + 1.5 = 3.640054945 Reorder the terms: 1.5 + x = 3.640054945 Solving 1.5 + x = 3.640054945 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 3.640054945 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 3.640054945 + -1.5 x = 3.640054945 + -1.5 Combine like terms: 3.640054945 + -1.5 = 2.140054945 x = 2.140054945 Simplifying x = 2.140054945Subproblem 2
x + 1.5 = -3.640054945 Simplifying x + 1.5 = -3.640054945 Reorder the terms: 1.5 + x = -3.640054945 Solving 1.5 + x = -3.640054945 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -3.640054945 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -3.640054945 + -1.5 x = -3.640054945 + -1.5 Combine like terms: -3.640054945 + -1.5 = -5.140054945 x = -5.140054945 Simplifying x = -5.140054945Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.140054945, -5.140054945}
