Simplifying 3(x + -1) + -1(x + -6) = x2 + -2 Reorder the terms: 3(-1 + x) + -1(x + -6) = x2 + -2 (-1 * 3 + x * 3) + -1(x + -6) = x2 + -2 (-3 + 3x) + -1(x + -6) = x2 + -2 Reorder the terms: -3 + 3x + -1(-6 + x) = x2 + -2 -3 + 3x + (-6 * -1 + x * -1) = x2 + -2 -3 + 3x + (6 + -1x) = x2 + -2 Reorder the terms: -3 + 6 + 3x + -1x = x2 + -2 Combine like terms: -3 + 6 = 3 3 + 3x + -1x = x2 + -2 Combine like terms: 3x + -1x = 2x 3 + 2x = x2 + -2 Reorder the terms: 3 + 2x = -2 + x2 Solving 3 + 2x = -2 + x2 Solving for variable 'x'. Reorder the terms: 3 + 2 + 2x + -1x2 = -2 + x2 + 2 + -1x2 Combine like terms: 3 + 2 = 5 5 + 2x + -1x2 = -2 + x2 + 2 + -1x2 Reorder the terms: 5 + 2x + -1x2 = -2 + 2 + x2 + -1x2 Combine like terms: -2 + 2 = 0 5 + 2x + -1x2 = 0 + x2 + -1x2 5 + 2x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 5 + 2x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -5 + -2x + x2 = 0 Move the constant term to the right: Add '5' to each side of the equation. -5 + -2x + 5 + x2 = 0 + 5 Reorder the terms: -5 + 5 + -2x + x2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -2x + x2 = 0 + 5 -2x + x2 = 0 + 5 Combine like terms: 0 + 5 = 5 -2x + x2 = 5 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 5 + 1 Reorder the terms: 1 + -2x + x2 = 5 + 1 Combine like terms: 5 + 1 = 6 1 + -2x + x2 = 6 Factor a perfect square on the left side: (x + -1)(x + -1) = 6 Calculate the square root of the right side: 2.449489743 Break this problem into two subproblems by setting (x + -1) equal to 2.449489743 and -2.449489743.Subproblem 1
x + -1 = 2.449489743 Simplifying x + -1 = 2.449489743 Reorder the terms: -1 + x = 2.449489743 Solving -1 + x = 2.449489743 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 2.449489743 + 1 Combine like terms: -1 + 1 = 0 0 + x = 2.449489743 + 1 x = 2.449489743 + 1 Combine like terms: 2.449489743 + 1 = 3.449489743 x = 3.449489743 Simplifying x = 3.449489743Subproblem 2
x + -1 = -2.449489743 Simplifying x + -1 = -2.449489743 Reorder the terms: -1 + x = -2.449489743 Solving -1 + x = -2.449489743 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -2.449489743 + 1 Combine like terms: -1 + 1 = 0 0 + x = -2.449489743 + 1 x = -2.449489743 + 1 Combine like terms: -2.449489743 + 1 = -1.449489743 x = -1.449489743 Simplifying x = -1.449489743Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.449489743, -1.449489743}
