Simplifying 2x(x + -3) = 4x + -20 Reorder the terms: 2x(-3 + x) = 4x + -20 (-3 * 2x + x * 2x) = 4x + -20 (-6x + 2x2) = 4x + -20 Reorder the terms: -6x + 2x2 = -20 + 4x Solving -6x + 2x2 = -20 + 4x Solving for variable 'x'. Reorder the terms: 20 + -6x + -4x + 2x2 = -20 + 4x + 20 + -4x Combine like terms: -6x + -4x = -10x 20 + -10x + 2x2 = -20 + 4x + 20 + -4x Reorder the terms: 20 + -10x + 2x2 = -20 + 20 + 4x + -4x Combine like terms: -20 + 20 = 0 20 + -10x + 2x2 = 0 + 4x + -4x 20 + -10x + 2x2 = 4x + -4x Combine like terms: 4x + -4x = 0 20 + -10x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(10 + -5x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(10 + -5x + x2)' equal to zero and attempt to solve: Simplifying 10 + -5x + x2 = 0 Solving 10 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-10' to each side of the equation. 10 + -5x + -10 + x2 = 0 + -10 Reorder the terms: 10 + -10 + -5x + x2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -5x + x2 = 0 + -10 -5x + x2 = 0 + -10 Combine like terms: 0 + -10 = -10 -5x + x2 = -10 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 = -10 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -10 + 6.25 Combine like terms: -10 + 6.25 = -3.75 6.25 + -5x + x2 = -3.75 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = -3.75 Can't calculate square root of the right side. The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
