Simplifying (2x + 5)(x + -4) = 6 Reorder the terms: (5 + 2x)(x + -4) = 6 Reorder the terms: (5 + 2x)(-4 + x) = 6 Multiply (5 + 2x) * (-4 + x) (5(-4 + x) + 2x * (-4 + x)) = 6 ((-4 * 5 + x * 5) + 2x * (-4 + x)) = 6 ((-20 + 5x) + 2x * (-4 + x)) = 6 (-20 + 5x + (-4 * 2x + x * 2x)) = 6 (-20 + 5x + (-8x + 2x2)) = 6 Combine like terms: 5x + -8x = -3x (-20 + -3x + 2x2) = 6 Solving -20 + -3x + 2x2 = 6 Solving for variable 'x'. Reorder the terms: -20 + -6 + -3x + 2x2 = 6 + -6 Combine like terms: -20 + -6 = -26 -26 + -3x + 2x2 = 6 + -6 Combine like terms: 6 + -6 = 0 -26 + -3x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -13 + -1.5x + x2 = 0 Move the constant term to the right: Add '13' to each side of the equation. -13 + -1.5x + 13 + x2 = 0 + 13 Reorder the terms: -13 + 13 + -1.5x + x2 = 0 + 13 Combine like terms: -13 + 13 = 0 0 + -1.5x + x2 = 0 + 13 -1.5x + x2 = 0 + 13 Combine like terms: 0 + 13 = 13 -1.5x + x2 = 13 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 13 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 13 + 0.5625 Combine like terms: 13 + 0.5625 = 13.5625 0.5625 + -1.5x + x2 = 13.5625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 13.5625 Calculate the square root of the right side: 3.682729966 Break this problem into two subproblems by setting (x + -0.75) equal to 3.682729966 and -3.682729966.Subproblem 1
x + -0.75 = 3.682729966 Simplifying x + -0.75 = 3.682729966 Reorder the terms: -0.75 + x = 3.682729966 Solving -0.75 + x = 3.682729966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 3.682729966 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 3.682729966 + 0.75 x = 3.682729966 + 0.75 Combine like terms: 3.682729966 + 0.75 = 4.432729966 x = 4.432729966 Simplifying x = 4.432729966Subproblem 2
x + -0.75 = -3.682729966 Simplifying x + -0.75 = -3.682729966 Reorder the terms: -0.75 + x = -3.682729966 Solving -0.75 + x = -3.682729966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -3.682729966 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -3.682729966 + 0.75 x = -3.682729966 + 0.75 Combine like terms: -3.682729966 + 0.75 = -2.932729966 x = -2.932729966 Simplifying x = -2.932729966Solution
