Simplifying 2x(x + 2) = -12 Reorder the terms: 2x(2 + x) = -12 (2 * 2x + x * 2x) = -12 (4x + 2x2) = -12 Solving 4x + 2x2 = -12 Solving for variable 'x'. Reorder the terms: 12 + 4x + 2x2 = -12 + 12 Combine like terms: -12 + 12 = 0 12 + 4x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(6 + 2x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(6 + 2x + x2)' equal to zero and attempt to solve: Simplifying 6 + 2x + x2 = 0 Solving 6 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-6' to each side of the equation. 6 + 2x + -6 + x2 = 0 + -6 Reorder the terms: 6 + -6 + 2x + x2 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + 2x + x2 = 0 + -6 2x + x2 = 0 + -6 Combine like terms: 0 + -6 = -6 2x + x2 = -6 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = -6 + 1 Reorder the terms: 1 + 2x + x2 = -6 + 1 Combine like terms: -6 + 1 = -5 1 + 2x + x2 = -5 Factor a perfect square on the left side: (x + 1)(x + 1) = -5 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.
