Simplifying x = 3x2 + 6x + 3 Reorder the terms: x = 3 + 6x + 3x2 Solving x = 3 + 6x + 3x2 Solving for variable 'x'. Reorder the terms: -3 + x + -6x + -3x2 = 3 + 6x + 3x2 + -3 + -6x + -3x2 Combine like terms: x + -6x = -5x -3 + -5x + -3x2 = 3 + 6x + 3x2 + -3 + -6x + -3x2 Reorder the terms: -3 + -5x + -3x2 = 3 + -3 + 6x + -6x + 3x2 + -3x2 Combine like terms: 3 + -3 = 0 -3 + -5x + -3x2 = 0 + 6x + -6x + 3x2 + -3x2 -3 + -5x + -3x2 = 6x + -6x + 3x2 + -3x2 Combine like terms: 6x + -6x = 0 -3 + -5x + -3x2 = 0 + 3x2 + -3x2 -3 + -5x + -3x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 -3 + -5x + -3x2 = 0 Factor out the Greatest Common Factor (GCF), '-1'. -1(3 + 5x + 3x2) = 0 Ignore the factor -1.Subproblem 1
Set the factor '(3 + 5x + 3x2)' equal to zero and attempt to solve: Simplifying 3 + 5x + 3x2 = 0 Solving 3 + 5x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. 1 + 1.666666667x + x2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + 1.666666667x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + 1.666666667x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 1.666666667x + x2 = 0 + -1 1.666666667x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 1.666666667x + x2 = -1 The x term is 1.666666667x. Take half its coefficient (0.8333333335). Square it (0.6944444447) and add it to both sides. Add '0.6944444447' to each side of the equation. 1.666666667x + 0.6944444447 + x2 = -1 + 0.6944444447 Reorder the terms: 0.6944444447 + 1.666666667x + x2 = -1 + 0.6944444447 Combine like terms: -1 + 0.6944444447 = -0.3055555553 0.6944444447 + 1.666666667x + x2 = -0.3055555553 Factor a perfect square on the left side: (x + 0.8333333335)(x + 0.8333333335) = -0.3055555553 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.
