Simplifying (4x + 1)(x + 2) = -2 Reorder the terms: (1 + 4x)(x + 2) = -2 Reorder the terms: (1 + 4x)(2 + x) = -2 Multiply (1 + 4x) * (2 + x) (1(2 + x) + 4x * (2 + x)) = -2 ((2 * 1 + x * 1) + 4x * (2 + x)) = -2 ((2 + 1x) + 4x * (2 + x)) = -2 (2 + 1x + (2 * 4x + x * 4x)) = -2 (2 + 1x + (8x + 4x2)) = -2 Combine like terms: 1x + 8x = 9x (2 + 9x + 4x2) = -2 Solving 2 + 9x + 4x2 = -2 Solving for variable 'x'. Reorder the terms: 2 + 2 + 9x + 4x2 = -2 + 2 Combine like terms: 2 + 2 = 4 4 + 9x + 4x2 = -2 + 2 Combine like terms: -2 + 2 = 0 4 + 9x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1 + 2.25x + x2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + 2.25x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + 2.25x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 2.25x + x2 = 0 + -1 2.25x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 2.25x + x2 = -1 The x term is 2.25x. Take half its coefficient (1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. 2.25x + 1.265625 + x2 = -1 + 1.265625 Reorder the terms: 1.265625 + 2.25x + x2 = -1 + 1.265625 Combine like terms: -1 + 1.265625 = 0.265625 1.265625 + 2.25x + x2 = 0.265625 Factor a perfect square on the left side: (x + 1.125)(x + 1.125) = 0.265625 Calculate the square root of the right side: 0.515388203 Break this problem into two subproblems by setting (x + 1.125) equal to 0.515388203 and -0.515388203.Subproblem 1
x + 1.125 = 0.515388203 Simplifying x + 1.125 = 0.515388203 Reorder the terms: 1.125 + x = 0.515388203 Solving 1.125 + x = 0.515388203 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + x = 0.515388203 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = 0.515388203 + -1.125 x = 0.515388203 + -1.125 Combine like terms: 0.515388203 + -1.125 = -0.609611797 x = -0.609611797 Simplifying x = -0.609611797Subproblem 2
x + 1.125 = -0.515388203 Simplifying x + 1.125 = -0.515388203 Reorder the terms: 1.125 + x = -0.515388203 Solving 1.125 + x = -0.515388203 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + x = -0.515388203 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = -0.515388203 + -1.125 x = -0.515388203 + -1.125 Combine like terms: -0.515388203 + -1.125 = -1.640388203 x = -1.640388203 Simplifying x = -1.640388203Solution
