Simplifying 2x2 + 142 + -24x = 0 Reorder the terms: 142 + -24x + 2x2 = 0 Solving 142 + -24x + 2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(71 + -12x + x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(71 + -12x + x2)' equal to zero and attempt to solve: Simplifying 71 + -12x + x2 = 0 Solving 71 + -12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-71' to each side of the equation. 71 + -12x + -71 + x2 = 0 + -71 Reorder the terms: 71 + -71 + -12x + x2 = 0 + -71 Combine like terms: 71 + -71 = 0 0 + -12x + x2 = 0 + -71 -12x + x2 = 0 + -71 Combine like terms: 0 + -71 = -71 -12x + x2 = -71 The x term is -12x. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12x + 36 + x2 = -71 + 36 Reorder the terms: 36 + -12x + x2 = -71 + 36 Combine like terms: -71 + 36 = -35 36 + -12x + x2 = -35 Factor a perfect square on the left side: (x + -6)(x + -6) = -35 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.
