Simplifying 15 + -2x = -4x(x + 1) + 9 Reorder the terms: 15 + -2x = -4x(1 + x) + 9 15 + -2x = (1 * -4x + x * -4x) + 9 15 + -2x = (-4x + -4x2) + 9 Reorder the terms: 15 + -2x = 9 + -4x + -4x2 Solving 15 + -2x = 9 + -4x + -4x2 Solving for variable 'x'. Reorder the terms: 15 + -9 + -2x + 4x + 4x2 = 9 + -4x + -4x2 + -9 + 4x + 4x2 Combine like terms: 15 + -9 = 6 6 + -2x + 4x + 4x2 = 9 + -4x + -4x2 + -9 + 4x + 4x2 Combine like terms: -2x + 4x = 2x 6 + 2x + 4x2 = 9 + -4x + -4x2 + -9 + 4x + 4x2 Reorder the terms: 6 + 2x + 4x2 = 9 + -9 + -4x + 4x + -4x2 + 4x2 Combine like terms: 9 + -9 = 0 6 + 2x + 4x2 = 0 + -4x + 4x + -4x2 + 4x2 6 + 2x + 4x2 = -4x + 4x + -4x2 + 4x2 Combine like terms: -4x + 4x = 0 6 + 2x + 4x2 = 0 + -4x2 + 4x2 6 + 2x + 4x2 = -4x2 + 4x2 Combine like terms: -4x2 + 4x2 = 0 6 + 2x + 4x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(3 + x + 2x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(3 + x + 2x2)' equal to zero and attempt to solve: Simplifying 3 + x + 2x2 = 0 Solving 3 + x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 1.5 + 0.5x + x2 = 0 Move the constant term to the right: Add '-1.5' to each side of the equation. 1.5 + 0.5x + -1.5 + x2 = 0 + -1.5 Reorder the terms: 1.5 + -1.5 + 0.5x + x2 = 0 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + 0.5x + x2 = 0 + -1.5 0.5x + x2 = 0 + -1.5 Combine like terms: 0 + -1.5 = -1.5 0.5x + x2 = -1.5 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.5x + 0.25 + x2 = -1.5 + 0.25 Reorder the terms: 0.25 + 0.5x + x2 = -1.5 + 0.25 Combine like terms: -1.5 + 0.25 = -1.25 0.25 + 0.5x + x2 = -1.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = -1.25 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.
