Simplifying (2x + -1)(3x + 4) = 8 Reorder the terms: (-1 + 2x)(3x + 4) = 8 Reorder the terms: (-1 + 2x)(4 + 3x) = 8 Multiply (-1 + 2x) * (4 + 3x) (-1(4 + 3x) + 2x * (4 + 3x)) = 8 ((4 * -1 + 3x * -1) + 2x * (4 + 3x)) = 8 ((-4 + -3x) + 2x * (4 + 3x)) = 8 (-4 + -3x + (4 * 2x + 3x * 2x)) = 8 (-4 + -3x + (8x + 6x2)) = 8 Combine like terms: -3x + 8x = 5x (-4 + 5x + 6x2) = 8 Solving -4 + 5x + 6x2 = 8 Solving for variable 'x'. Reorder the terms: -4 + -8 + 5x + 6x2 = 8 + -8 Combine like terms: -4 + -8 = -12 -12 + 5x + 6x2 = 8 + -8 Combine like terms: 8 + -8 = 0 -12 + 5x + 6x2 = 0 Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. -2 + 0.8333333333x + x2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + 0.8333333333x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 0.8333333333x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 0.8333333333x + x2 = 0 + 2 0.8333333333x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 0.8333333333x + x2 = 2 The x term is 0.8333333333x. Take half its coefficient (0.4166666667). Square it (0.1736111111) and add it to both sides. Add '0.1736111111' to each side of the equation. 0.8333333333x + 0.1736111111 + x2 = 2 + 0.1736111111 Reorder the terms: 0.1736111111 + 0.8333333333x + x2 = 2 + 0.1736111111 Combine like terms: 2 + 0.1736111111 = 2.1736111111 0.1736111111 + 0.8333333333x + x2 = 2.1736111111 Factor a perfect square on the left side: (x + 0.4166666667)(x + 0.4166666667) = 2.1736111111 Calculate the square root of the right side: 1.474317168 Break this problem into two subproblems by setting (x + 0.4166666667) equal to 1.474317168 and -1.474317168.Subproblem 1
