Simplifying (x + -2)(x + 1) = 3 Reorder the terms: (-2 + x)(x + 1) = 3 Reorder the terms: (-2 + x)(1 + x) = 3 Multiply (-2 + x) * (1 + x) (-2(1 + x) + x(1 + x)) = 3 ((1 * -2 + x * -2) + x(1 + x)) = 3 ((-2 + -2x) + x(1 + x)) = 3 (-2 + -2x + (1 * x + x * x)) = 3 (-2 + -2x + (1x + x2)) = 3 Combine like terms: -2x + 1x = -1x (-2 + -1x + x2) = 3 Solving -2 + -1x + x2 = 3 Solving for variable 'x'. Reorder the terms: -2 + -3 + -1x + x2 = 3 + -3 Combine like terms: -2 + -3 = -5 -5 + -1x + x2 = 3 + -3 Combine like terms: 3 + -3 = 0 -5 + -1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + -1x + 5 + x2 = 0 + 5 Reorder the terms: -5 + 5 + -1x + x2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -1x + x2 = 0 + 5 -1x + x2 = 0 + 5 Combine like terms: 0 + 5 = 5 -1x + x2 = 5 The x term is -1x. 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. -1x + 0.25 + x2 = 5 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 5 + 0.25 Combine like terms: 5 + 0.25 = 5.25 0.25 + -1x + x2 = 5.25 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 5.25 Calculate the square root of the right side: 2.291287847 Break this problem into two subproblems by setting (x + -0.5) equal to 2.291287847 and -2.291287847.Subproblem 1
x + -0.5 = 2.291287847 Simplifying x + -0.5 = 2.291287847 Reorder the terms: -0.5 + x = 2.291287847 Solving -0.5 + x = 2.291287847 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 = 2.291287847 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 2.291287847 + 0.5 x = 2.291287847 + 0.5 Combine like terms: 2.291287847 + 0.5 = 2.791287847 x = 2.791287847 Simplifying x = 2.791287847Subproblem 2
x + -0.5 = -2.291287847 Simplifying x + -0.5 = -2.291287847 Reorder the terms: -0.5 + x = -2.291287847 Solving -0.5 + x = -2.291287847 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 = -2.291287847 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -2.291287847 + 0.5 x = -2.291287847 + 0.5 Combine like terms: -2.291287847 + 0.5 = -1.791287847 x = -1.791287847 Simplifying x = -1.791287847Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.791287847, -1.791287847}
