Simplifying -2x(x + -3) = 16 Reorder the terms: -2x(-3 + x) = 16 (-3 * -2x + x * -2x) = 16 (6x + -2x2) = 16 Solving 6x + -2x2 = 16 Solving for variable 'x'. Reorder the terms: -16 + 6x + -2x2 = 16 + -16 Combine like terms: 16 + -16 = 0 -16 + 6x + -2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(-8 + 3x + -1x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-8 + 3x + -1x2)' equal to zero and attempt to solve: Simplifying -8 + 3x + -1x2 = 0 Solving -8 + 3x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 8 + -3x + x2 = 0 Move the constant term to the right: Add '-8' to each side of the equation. 8 + -3x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + -3x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -3x + x2 = 0 + -8 -3x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 -3x + x2 = -8 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = -8 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -8 + 2.25 Combine like terms: -8 + 2.25 = -5.75 2.25 + -3x + x2 = -5.75 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = -5.75 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.
