Simplifying 3x + -1(-2x + 6) = 4x(x + -4) + x Reorder the terms: 3x + -1(6 + -2x) = 4x(x + -4) + x 3x + (6 * -1 + -2x * -1) = 4x(x + -4) + x 3x + (-6 + 2x) = 4x(x + -4) + x Reorder the terms: -6 + 3x + 2x = 4x(x + -4) + x Combine like terms: 3x + 2x = 5x -6 + 5x = 4x(x + -4) + x Reorder the terms: -6 + 5x = 4x(-4 + x) + x -6 + 5x = (-4 * 4x + x * 4x) + x -6 + 5x = (-16x + 4x2) + x Reorder the terms: -6 + 5x = -16x + x + 4x2 Combine like terms: -16x + x = -15x -6 + 5x = -15x + 4x2 Solving -6 + 5x = -15x + 4x2 Solving for variable 'x'. Combine like terms: 5x + 15x = 20x -6 + 20x + -4x2 = -15x + 4x2 + 15x + -4x2 Reorder the terms: -6 + 20x + -4x2 = -15x + 15x + 4x2 + -4x2 Combine like terms: -15x + 15x = 0 -6 + 20x + -4x2 = 0 + 4x2 + -4x2 -6 + 20x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 -6 + 20x + -4x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-3 + 10x + -2x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-3 + 10x + -2x2)' equal to zero and attempt to solve: Simplifying -3 + 10x + -2x2 = 0 Solving -3 + 10x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 1.5 + -5x + x2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + -5x + -1.5 + x2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + -5x + x2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + -5x + x2 = 0 + -1.5 -5x + x2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 -5x + x2 = -1.5 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -1.5 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -1.5 + 6.25 Combine like terms: -1.5 + 6.25 = 4.75 6.25 + -5x + x2 = 4.75 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 4.75 Calculate the square root of the right side: 2.179449472 Break this problem into two subproblems by setting (x + -2.5) equal to 2.179449472 and -2.179449472.Subproblem 1
x + -2.5 = 2.179449472 Simplifying x + -2.5 = 2.179449472 Reorder the terms: -2.5 + x = 2.179449472 Solving -2.5 + x = 2.179449472 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 2.179449472 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 2.179449472 + 2.5 x = 2.179449472 + 2.5 Combine like terms: 2.179449472 + 2.5 = 4.679449472 x = 4.679449472 Simplifying x = 4.679449472Subproblem 2
x + -2.5 = -2.179449472 Simplifying x + -2.5 = -2.179449472 Reorder the terms: -2.5 + x = -2.179449472 Solving -2.5 + x = -2.179449472 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -2.179449472 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -2.179449472 + 2.5 x = -2.179449472 + 2.5 Combine like terms: -2.179449472 + 2.5 = 0.320550528 x = 0.320550528 Simplifying x = 0.320550528Solution
