Simplifying 3x + 8x = x2 + -3x + -12 Combine like terms: 3x + 8x = 11x 11x = x2 + -3x + -12 Reorder the terms: 11x = -12 + -3x + x2 Solving 11x = -12 + -3x + x2 Solving for variable 'x'. Reorder the terms: 12 + 11x + 3x + -1x2 = -12 + -3x + x2 + 12 + 3x + -1x2 Combine like terms: 11x + 3x = 14x 12 + 14x + -1x2 = -12 + -3x + x2 + 12 + 3x + -1x2 Reorder the terms: 12 + 14x + -1x2 = -12 + 12 + -3x + 3x + x2 + -1x2 Combine like terms: -12 + 12 = 0 12 + 14x + -1x2 = 0 + -3x + 3x + x2 + -1x2 12 + 14x + -1x2 = -3x + 3x + x2 + -1x2 Combine like terms: -3x + 3x = 0 12 + 14x + -1x2 = 0 + x2 + -1x2 12 + 14x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 12 + 14x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -12 + -14x + x2 = 0 Move the constant term to the right: Add '12' to each side of the equation. -12 + -14x + 12 + x2 = 0 + 12 Reorder the terms: -12 + 12 + -14x + x2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + -14x + x2 = 0 + 12 -14x + x2 = 0 + 12 Combine like terms: 0 + 12 = 12 -14x + x2 = 12 The x term is -14x. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14x + 49 + x2 = 12 + 49 Reorder the terms: 49 + -14x + x2 = 12 + 49 Combine like terms: 12 + 49 = 61 49 + -14x + x2 = 61 Factor a perfect square on the left side: (x + -7)(x + -7) = 61 Calculate the square root of the right side: 7.810249676 Break this problem into two subproblems by setting (x + -7) equal to 7.810249676 and -7.810249676.Subproblem 1
x + -7 = 7.810249676 Simplifying x + -7 = 7.810249676 Reorder the terms: -7 + x = 7.810249676 Solving -7 + x = 7.810249676 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + x = 7.810249676 + 7 Combine like terms: -7 + 7 = 0 0 + x = 7.810249676 + 7 x = 7.810249676 + 7 Combine like terms: 7.810249676 + 7 = 14.810249676 x = 14.810249676 Simplifying x = 14.810249676Subproblem 2
x + -7 = -7.810249676 Simplifying x + -7 = -7.810249676 Reorder the terms: -7 + x = -7.810249676 Solving -7 + x = -7.810249676 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + x = -7.810249676 + 7 Combine like terms: -7 + 7 = 0 0 + x = -7.810249676 + 7 x = -7.810249676 + 7 Combine like terms: -7.810249676 + 7 = -0.810249676 x = -0.810249676 Simplifying x = -0.810249676Solution
The solution to the problem is based on the solutions from the subproblems. x = {14.810249676, -0.810249676}
