Simplifying (2x + 9)(x + -5) = 50 Reorder the terms: (9 + 2x)(x + -5) = 50 Reorder the terms: (9 + 2x)(-5 + x) = 50 Multiply (9 + 2x) * (-5 + x) (9(-5 + x) + 2x * (-5 + x)) = 50 ((-5 * 9 + x * 9) + 2x * (-5 + x)) = 50 ((-45 + 9x) + 2x * (-5 + x)) = 50 (-45 + 9x + (-5 * 2x + x * 2x)) = 50 (-45 + 9x + (-10x + 2x2)) = 50 Combine like terms: 9x + -10x = -1x (-45 + -1x + 2x2) = 50 Solving -45 + -1x + 2x2 = 50 Solving for variable 'x'. Reorder the terms: -45 + -50 + -1x + 2x2 = 50 + -50 Combine like terms: -45 + -50 = -95 -95 + -1x + 2x2 = 50 + -50 Combine like terms: 50 + -50 = 0 -95 + -1x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -47.5 + -0.5x + x2 = 0 Move the constant term to the right: Add '47.5' to each side of the equation. -47.5 + -0.5x + 47.5 + x2 = 0 + 47.5 Reorder the terms: -47.5 + 47.5 + -0.5x + x2 = 0 + 47.5 Combine like terms: -47.5 + 47.5 = 0.0 0.0 + -0.5x + x2 = 0 + 47.5 -0.5x + x2 = 0 + 47.5 Combine like terms: 0 + 47.5 = 47.5 -0.5x + x2 = 47.5 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 47.5 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 47.5 + 0.0625 Combine like terms: 47.5 + 0.0625 = 47.5625 0.0625 + -0.5x + x2 = 47.5625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 47.5625 Calculate the square root of the right side: 6.896557112 Break this problem into two subproblems by setting (x + -0.25) equal to 6.896557112 and -6.896557112.Subproblem 1
x + -0.25 = 6.896557112 Simplifying x + -0.25 = 6.896557112 Reorder the terms: -0.25 + x = 6.896557112 Solving -0.25 + x = 6.896557112 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 6.896557112 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 6.896557112 + 0.25 x = 6.896557112 + 0.25 Combine like terms: 6.896557112 + 0.25 = 7.146557112 x = 7.146557112 Simplifying x = 7.146557112Subproblem 2
x + -0.25 = -6.896557112 Simplifying x + -0.25 = -6.896557112 Reorder the terms: -0.25 + x = -6.896557112 Solving -0.25 + x = -6.896557112 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -6.896557112 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -6.896557112 + 0.25 x = -6.896557112 + 0.25 Combine like terms: -6.896557112 + 0.25 = -6.646557112 x = -6.646557112 Simplifying x = -6.646557112Solution
