Simplifying x2 + 50x = 1000 Reorder the terms: 50x + x2 = 1000 Solving 50x + x2 = 1000 Solving for variable 'x'. Reorder the terms: -1000 + 50x + x2 = 1000 + -1000 Combine like terms: 1000 + -1000 = 0 -1000 + 50x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '1000' to each side of the equation. -1000 + 50x + 1000 + x2 = 0 + 1000 Reorder the terms: -1000 + 1000 + 50x + x2 = 0 + 1000 Combine like terms: -1000 + 1000 = 0 0 + 50x + x2 = 0 + 1000 50x + x2 = 0 + 1000 Combine like terms: 0 + 1000 = 1000 50x + x2 = 1000 The x term is 50x. Take half its coefficient (25). Square it (625) and add it to both sides. Add '625' to each side of the equation. 50x + 625 + x2 = 1000 + 625 Reorder the terms: 625 + 50x + x2 = 1000 + 625 Combine like terms: 1000 + 625 = 1625 625 + 50x + x2 = 1625 Factor a perfect square on the left side: (x + 25)(x + 25) = 1625 Calculate the square root of the right side: 40.311288741 Break this problem into two subproblems by setting (x + 25) equal to 40.311288741 and -40.311288741.Subproblem 1
x + 25 = 40.311288741 Simplifying x + 25 = 40.311288741 Reorder the terms: 25 + x = 40.311288741 Solving 25 + x = 40.311288741 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-25' to each side of the equation. 25 + -25 + x = 40.311288741 + -25 Combine like terms: 25 + -25 = 0 0 + x = 40.311288741 + -25 x = 40.311288741 + -25 Combine like terms: 40.311288741 + -25 = 15.311288741 x = 15.311288741 Simplifying x = 15.311288741Subproblem 2
x + 25 = -40.311288741 Simplifying x + 25 = -40.311288741 Reorder the terms: 25 + x = -40.311288741 Solving 25 + x = -40.311288741 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-25' to each side of the equation. 25 + -25 + x = -40.311288741 + -25 Combine like terms: 25 + -25 = 0 0 + x = -40.311288741 + -25 x = -40.311288741 + -25 Combine like terms: -40.311288741 + -25 = -65.311288741 x = -65.311288741 Simplifying x = -65.311288741Solution
