Simplifying (20 + -1x)(40 + -1x) = 526 Multiply (20 + -1x) * (40 + -1x) (20(40 + -1x) + -1x * (40 + -1x)) = 526 ((40 * 20 + -1x * 20) + -1x * (40 + -1x)) = 526 ((800 + -20x) + -1x * (40 + -1x)) = 526 (800 + -20x + (40 * -1x + -1x * -1x)) = 526 (800 + -20x + (-40x + 1x2)) = 526 Combine like terms: -20x + -40x = -60x (800 + -60x + 1x2) = 526 Solving 800 + -60x + 1x2 = 526 Solving for variable 'x'. Reorder the terms: 800 + -526 + -60x + 1x2 = 526 + -526 Combine like terms: 800 + -526 = 274 274 + -60x + 1x2 = 526 + -526 Combine like terms: 526 + -526 = 0 274 + -60x + 1x2 = 0 Begin completing the square. Move the constant term to the right: Add '-274' to each side of the equation. 274 + -60x + -274 + x2 = 0 + -274 Reorder the terms: 274 + -274 + -60x + x2 = 0 + -274 Combine like terms: 274 + -274 = 0 0 + -60x + x2 = 0 + -274 -60x + x2 = 0 + -274 Combine like terms: 0 + -274 = -274 -60x + x2 = -274 The x term is -60x. Take half its coefficient (-30). Square it (900) and add it to both sides. Add '900' to each side of the equation. -60x + 900 + x2 = -274 + 900 Reorder the terms: 900 + -60x + x2 = -274 + 900 Combine like terms: -274 + 900 = 626 900 + -60x + x2 = 626 Factor a perfect square on the left side: (x + -30)(x + -30) = 626 Calculate the square root of the right side: 25.019992006 Break this problem into two subproblems by setting (x + -30) equal to 25.019992006 and -25.019992006.Subproblem 1
x + -30 = 25.019992006 Simplifying x + -30 = 25.019992006 Reorder the terms: -30 + x = 25.019992006 Solving -30 + x = 25.019992006 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '30' to each side of the equation. -30 + 30 + x = 25.019992006 + 30 Combine like terms: -30 + 30 = 0 0 + x = 25.019992006 + 30 x = 25.019992006 + 30 Combine like terms: 25.019992006 + 30 = 55.019992006 x = 55.019992006 Simplifying x = 55.019992006Subproblem 2
x + -30 = -25.019992006 Simplifying x + -30 = -25.019992006 Reorder the terms: -30 + x = -25.019992006 Solving -30 + x = -25.019992006 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '30' to each side of the equation. -30 + 30 + x = -25.019992006 + 30 Combine like terms: -30 + 30 = 0 0 + x = -25.019992006 + 30 x = -25.019992006 + 30 Combine like terms: -25.019992006 + 30 = 4.980007994 x = 4.980007994 Simplifying x = 4.980007994Solution
The solution to the problem is based on the solutions from the subproblems. x = {55.019992006, 4.980007994}
