Simplifying 3x2 + -12x + 38 = -3x2 + -10x Reorder the terms: 38 + -12x + 3x2 = -3x2 + -10x Reorder the terms: 38 + -12x + 3x2 = -10x + -3x2 Solving 38 + -12x + 3x2 = -10x + -3x2 Solving for variable 'x'. Reorder the terms: 38 + -12x + 10x + 3x2 + 3x2 = -10x + -3x2 + 10x + 3x2 Combine like terms: -12x + 10x = -2x 38 + -2x + 3x2 + 3x2 = -10x + -3x2 + 10x + 3x2 Combine like terms: 3x2 + 3x2 = 6x2 38 + -2x + 6x2 = -10x + -3x2 + 10x + 3x2 Reorder the terms: 38 + -2x + 6x2 = -10x + 10x + -3x2 + 3x2 Combine like terms: -10x + 10x = 0 38 + -2x + 6x2 = 0 + -3x2 + 3x2 38 + -2x + 6x2 = -3x2 + 3x2 Combine like terms: -3x2 + 3x2 = 0 38 + -2x + 6x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(19 + -1x + 3x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(19 + -1x + 3x2)' equal to zero and attempt to solve: Simplifying 19 + -1x + 3x2 = 0 Solving 19 + -1x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 6.333333333 + -0.3333333333x + x2 = 0 Move the constant term to the right: Add '-6.333333333' to each side of the equation. 6.333333333 + -0.3333333333x + -6.333333333 + x2 = 0 + -6.333333333 Reorder the terms: 6.333333333 + -6.333333333 + -0.3333333333x + x2 = 0 + -6.333333333 Combine like terms: 6.333333333 + -6.333333333 = 0.000000000 0.000000000 + -0.3333333333x + x2 = 0 + -6.333333333 -0.3333333333x + x2 = 0 + -6.333333333 Combine like terms: 0 + -6.333333333 = -6.333333333 -0.3333333333x + x2 = -6.333333333 The x term is -0.3333333333x. Take half its coefficient (-0.1666666667). Square it (0.02777777779) and add it to both sides. Add '0.02777777779' to each side of the equation. -0.3333333333x + 0.02777777779 + x2 = -6.333333333 + 0.02777777779 Reorder the terms: 0.02777777779 + -0.3333333333x + x2 = -6.333333333 + 0.02777777779 Combine like terms: -6.333333333 + 0.02777777779 = -6.30555555521 0.02777777779 + -0.3333333333x + x2 = -6.30555555521 Factor a perfect square on the left side: (x + -0.1666666667)(x + -0.1666666667) = -6.30555555521 Can't calculate square root of the right side.
