Simplifying (-5x + 4)(x + 2) + 2x = 0 Reorder the terms: (4 + -5x)(x + 2) + 2x = 0 Reorder the terms: (4 + -5x)(2 + x) + 2x = 0 Multiply (4 + -5x) * (2 + x) (4(2 + x) + -5x * (2 + x)) + 2x = 0 ((2 * 4 + x * 4) + -5x * (2 + x)) + 2x = 0 ((8 + 4x) + -5x * (2 + x)) + 2x = 0 (8 + 4x + (2 * -5x + x * -5x)) + 2x = 0 (8 + 4x + (-10x + -5x2)) + 2x = 0 Combine like terms: 4x + -10x = -6x (8 + -6x + -5x2) + 2x = 0 Reorder the terms: 8 + -6x + 2x + -5x2 = 0 Combine like terms: -6x + 2x = -4x 8 + -4x + -5x2 = 0 Solving 8 + -4x + -5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -1.6 + 0.8x + x2 = 0 Move the constant term to the right: Add '1.6' to each side of the equation. -1.6 + 0.8x + 1.6 + x2 = 0 + 1.6 Reorder the terms: -1.6 + 1.6 + 0.8x + x2 = 0 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + 0.8x + x2 = 0 + 1.6 0.8x + x2 = 0 + 1.6 Combine like terms: 0 + 1.6 = 1.6 0.8x + x2 = 1.6 The x term is 0.8x. Take half its coefficient (0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. 0.8x + 0.16 + x2 = 1.6 + 0.16 Reorder the terms: 0.16 + 0.8x + x2 = 1.6 + 0.16 Combine like terms: 1.6 + 0.16 = 1.76 0.16 + 0.8x + x2 = 1.76 Factor a perfect square on the left side: (x + 0.4)(x + 0.4) = 1.76 Calculate the square root of the right side: 1.326649916 Break this problem into two subproblems by setting (x + 0.4) equal to 1.326649916 and -1.326649916.Subproblem 1
x + 0.4 = 1.326649916 Simplifying x + 0.4 = 1.326649916 Reorder the terms: 0.4 + x = 1.326649916 Solving 0.4 + x = 1.326649916 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = 1.326649916 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = 1.326649916 + -0.4 x = 1.326649916 + -0.4 Combine like terms: 1.326649916 + -0.4 = 0.926649916 x = 0.926649916 Simplifying x = 0.926649916Subproblem 2
x + 0.4 = -1.326649916 Simplifying x + 0.4 = -1.326649916 Reorder the terms: 0.4 + x = -1.326649916 Solving 0.4 + x = -1.326649916 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.4' to each side of the equation. 0.4 + -0.4 + x = -1.326649916 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + x = -1.326649916 + -0.4 x = -1.326649916 + -0.4 Combine like terms: -1.326649916 + -0.4 = -1.726649916 x = -1.726649916 Simplifying x = -1.726649916Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.926649916, -1.726649916}
