Simplifying (3x + -1)(3x + -1) = 28 Reorder the terms: (-1 + 3x)(3x + -1) = 28 Reorder the terms: (-1 + 3x)(-1 + 3x) = 28 Multiply (-1 + 3x) * (-1 + 3x) (-1(-1 + 3x) + 3x * (-1 + 3x)) = 28 ((-1 * -1 + 3x * -1) + 3x * (-1 + 3x)) = 28 ((1 + -3x) + 3x * (-1 + 3x)) = 28 (1 + -3x + (-1 * 3x + 3x * 3x)) = 28 (1 + -3x + (-3x + 9x2)) = 28 Combine like terms: -3x + -3x = -6x (1 + -6x + 9x2) = 28 Solving 1 + -6x + 9x2 = 28 Solving for variable 'x'. Reorder the terms: 1 + -28 + -6x + 9x2 = 28 + -28 Combine like terms: 1 + -28 = -27 -27 + -6x + 9x2 = 28 + -28 Combine like terms: 28 + -28 = 0 -27 + -6x + 9x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-9 + -2x + 3x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-9 + -2x + 3x2)' equal to zero and attempt to solve: Simplifying -9 + -2x + 3x2 = 0 Solving -9 + -2x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -3 + -0.6666666667x + x2 = 0 Move the constant term to the right: Add '3' to each side of the equation. -3 + -0.6666666667x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + -0.6666666667x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -0.6666666667x + x2 = 0 + 3 -0.6666666667x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 -0.6666666667x + x2 = 3 The x term is -0.6666666667x. Take half its coefficient (-0.3333333334). Square it (0.1111111112) and add it to both sides. Add '0.1111111112' to each side of the equation. -0.6666666667x + 0.1111111112 + x2 = 3 + 0.1111111112 Reorder the terms: 0.1111111112 + -0.6666666667x + x2 = 3 + 0.1111111112 Combine like terms: 3 + 0.1111111112 = 3.1111111112 0.1111111112 + -0.6666666667x + x2 = 3.1111111112 Factor a perfect square on the left side: (x + -0.3333333334)(x + -0.3333333334) = 3.1111111112 Calculate the square root of the right side: 1.763834207 Break this problem into two subproblems by setting (x + -0.3333333334) equal to 1.763834207 and -1.763834207.Subproblem 1
