Simplifying (x + -4) + -4 = -4x(4 + -3x) Reorder the terms: (-4 + x) + -4 = -4x(4 + -3x) Remove parenthesis around (-4 + x) -4 + x + -4 = -4x(4 + -3x) Reorder the terms: -4 + -4 + x = -4x(4 + -3x) Combine like terms: -4 + -4 = -8 -8 + x = -4x(4 + -3x) -8 + x = (4 * -4x + -3x * -4x) -8 + x = (-16x + 12x2) Solving -8 + x = -16x + 12x2 Solving for variable 'x'. Combine like terms: x + 16x = 17x -8 + 17x + -12x2 = -16x + 12x2 + 16x + -12x2 Reorder the terms: -8 + 17x + -12x2 = -16x + 16x + 12x2 + -12x2 Combine like terms: -16x + 16x = 0 -8 + 17x + -12x2 = 0 + 12x2 + -12x2 -8 + 17x + -12x2 = 12x2 + -12x2 Combine like terms: 12x2 + -12x2 = 0 -8 + 17x + -12x2 = 0 Begin completing the square. Divide all terms by -12 the coefficient of the squared term: Divide each side by '-12'. 0.6666666667 + -1.416666667x + x2 = 0 Move the constant term to the right: Add '-0.6666666667' to each side of the equation. 0.6666666667 + -1.416666667x + -0.6666666667 + x2 = 0 + -0.6666666667 Reorder the terms: 0.6666666667 + -0.6666666667 + -1.416666667x + x2 = 0 + -0.6666666667 Combine like terms: 0.6666666667 + -0.6666666667 = 0.0000000000 0.0000000000 + -1.416666667x + x2 = 0 + -0.6666666667 -1.416666667x + x2 = 0 + -0.6666666667 Combine like terms: 0 + -0.6666666667 = -0.6666666667 -1.416666667x + x2 = -0.6666666667 The x term is -1.416666667x. Take half its coefficient (-0.7083333335). Square it (0.5017361113) and add it to both sides. Add '0.5017361113' to each side of the equation. -1.416666667x + 0.5017361113 + x2 = -0.6666666667 + 0.5017361113 Reorder the terms: 0.5017361113 + -1.416666667x + x2 = -0.6666666667 + 0.5017361113 Combine like terms: -0.6666666667 + 0.5017361113 = -0.1649305554 0.5017361113 + -1.416666667x + x2 = -0.1649305554 Factor a perfect square on the left side: (x + -0.7083333335)(x + -0.7083333335) = -0.1649305554 Can't calculate square root of the right side. The solution to this equation could not be determined.
