Simplifying (3x + -1)(x + 1) = 8 Reorder the terms: (-1 + 3x)(x + 1) = 8 Reorder the terms: (-1 + 3x)(1 + x) = 8 Multiply (-1 + 3x) * (1 + x) (-1(1 + x) + 3x * (1 + x)) = 8 ((1 * -1 + x * -1) + 3x * (1 + x)) = 8 ((-1 + -1x) + 3x * (1 + x)) = 8 (-1 + -1x + (1 * 3x + x * 3x)) = 8 (-1 + -1x + (3x + 3x2)) = 8 Combine like terms: -1x + 3x = 2x (-1 + 2x + 3x2) = 8 Solving -1 + 2x + 3x2 = 8 Solving for variable 'x'. Reorder the terms: -1 + -8 + 2x + 3x2 = 8 + -8 Combine like terms: -1 + -8 = -9 -9 + 2x + 3x2 = 8 + -8 Combine like terms: 8 + -8 = 0 -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
x + 0.3333333334 = 1.763834207 Simplifying x + 0.3333333334 = 1.763834207 Reorder the terms: 0.3333333334 + x = 1.763834207 Solving 0.3333333334 + x = 1.763834207 Solving for variable 'x'.
