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. x + 0.25 + x2 = 5 + 0.25 Reorder the terms: 0.25 + x + x2 = 5 + 0.25 Combine like terms: 5 + 0.25 = 5.25 0.25 + x + 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 = 1.791287847 x = 1.791287847 Simplifying x = 1.791287847Subproblem 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 = -2.791287847 x = -2.791287847 Simplifying x = -2.791287847Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.791287847, -2.791287847}
