Simplifying (25 + 2x)(15 + x) = 750 Multiply (25 + 2x) * (15 + x) (25(15 + x) + 2x * (15 + x)) = 750 ((15 * 25 + x * 25) + 2x * (15 + x)) = 750 ((375 + 25x) + 2x * (15 + x)) = 750 (375 + 25x + (15 * 2x + x * 2x)) = 750 (375 + 25x + (30x + 2x2)) = 750 Combine like terms: 25x + 30x = 55x (375 + 55x + 2x2) = 750 Solving 375 + 55x + 2x2 = 750 Solving for variable 'x'. Reorder the terms: 375 + -750 + 55x + 2x2 = 750 + -750 Combine like terms: 375 + -750 = -375 -375 + 55x + 2x2 = 750 + -750 Combine like terms: 750 + -750 = 0 -375 + 55x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -187.5 + 27.5x + x2 = 0 Move the constant term to the right: Add '187.5' to each side of the equation. -187.5 + 27.5x + 187.5 + x2 = 0 + 187.5 Reorder the terms: -187.5 + 187.5 + 27.5x + x2 = 0 + 187.5 Combine like terms: -187.5 + 187.5 = 0.0 0.0 + 27.5x + x2 = 0 + 187.5 27.5x + x2 = 0 + 187.5 Combine like terms: 0 + 187.5 = 187.5 27.5x + x2 = 187.5 The x term is 27.5x. Take half its coefficient (13.75). Square it (189.0625) and add it to both sides. Add '189.0625' to each side of the equation. 27.5x + 189.0625 + x2 = 187.5 + 189.0625 Reorder the terms: 189.0625 + 27.5x + x2 = 187.5 + 189.0625 Combine like terms: 187.5 + 189.0625 = 376.5625 189.0625 + 27.5x + x2 = 376.5625 Factor a perfect square on the left side: (x + 13.75)(x + 13.75) = 376.5625 Calculate the square root of the right side: 19.40521837 Break this problem into two subproblems by setting (x + 13.75) equal to 19.40521837 and -19.40521837.Subproblem 1
x + 13.75 = 19.40521837 Simplifying x + 13.75 = 19.40521837 Reorder the terms: 13.75 + x = 19.40521837 Solving 13.75 + x = 19.40521837 Solving for variable 'x'.
