Simplifying a2 + -2a = 100 Reorder the terms: -2a + a2 = 100 Solving -2a + a2 = 100 Solving for variable 'a'. Reorder the terms: -100 + -2a + a2 = 100 + -100 Combine like terms: 100 + -100 = 0 -100 + -2a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '100' to each side of the equation. -100 + -2a + 100 + a2 = 0 + 100 Reorder the terms: -100 + 100 + -2a + a2 = 0 + 100 Combine like terms: -100 + 100 = 0 0 + -2a + a2 = 0 + 100 -2a + a2 = 0 + 100 Combine like terms: 0 + 100 = 100 -2a + a2 = 100 The a term is -2a. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2a + 1 + a2 = 100 + 1 Reorder the terms: 1 + -2a + a2 = 100 + 1 Combine like terms: 100 + 1 = 101 1 + -2a + a2 = 101 Factor a perfect square on the left side: (a + -1)(a + -1) = 101 Calculate the square root of the right side: 10.049875621 Break this problem into two subproblems by setting (a + -1) equal to 10.049875621 and -10.049875621.Subproblem 1
a + -1 = 10.049875621 Simplifying a + -1 = 10.049875621 Reorder the terms: -1 + a = 10.049875621 Solving -1 + a = 10.049875621 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right.
