Simplifying a2 + -1000a + 240001 = 0 Reorder the terms: 240001 + -1000a + a2 = 0 Solving 240001 + -1000a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '-240001' to each side of the equation. 240001 + -1000a + -240001 + a2 = 0 + -240001 Reorder the terms: 240001 + -240001 + -1000a + a2 = 0 + -240001 Combine like terms: 240001 + -240001 = 0 0 + -1000a + a2 = 0 + -240001 -1000a + a2 = 0 + -240001 Combine like terms: 0 + -240001 = -240001 -1000a + a2 = -240001 The a term is -1000a. Take half its coefficient (-500). Square it (250000) and add it to both sides. Add '250000' to each side of the equation. -1000a + 250000 + a2 = -240001 + 250000 Reorder the terms: 250000 + -1000a + a2 = -240001 + 250000 Combine like terms: -240001 + 250000 = 9999 250000 + -1000a + a2 = 9999 Factor a perfect square on the left side: (a + -500)(a + -500) = 9999 Calculate the square root of the right side: 99.994999875 Break this problem into two subproblems by setting (a + -500) equal to 99.994999875 and -99.994999875.Subproblem 1
a + -500 = 99.994999875 Simplifying a + -500 = 99.994999875 Reorder the terms: -500 + a = 99.994999875 Solving -500 + a = 99.994999875 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '500' to each side of the equation. -500 + 500 + a = 99.994999875 + 500 Combine like terms: -500 + 500 = 0 0 + a = 99.994999875 + 500 a = 99.994999875 + 500 Combine like terms: 99.994999875 + 500 = 599.994999875 a = 599.994999875 Simplifying a = 599.994999875Subproblem 2
a + -500 = -99.994999875 Simplifying a + -500 = -99.994999875 Reorder the terms: -500 + a = -99.994999875 Solving -500 + a = -99.994999875 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '500' to each side of the equation. -500 + 500 + a = -99.994999875 + 500 Combine like terms: -500 + 500 = 0 0 + a = -99.994999875 + 500 a = -99.994999875 + 500 Combine like terms: -99.994999875 + 500 = 400.005000125 a = 400.005000125 Simplifying a = 400.005000125Solution
