Simplifying a2 + 2a + -79 = 0 Reorder the terms: -79 + 2a + a2 = 0 Solving -79 + 2a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '79' to each side of the equation. -79 + 2a + 79 + a2 = 0 + 79 Reorder the terms: -79 + 79 + 2a + a2 = 0 + 79 Combine like terms: -79 + 79 = 0 0 + 2a + a2 = 0 + 79 2a + a2 = 0 + 79 Combine like terms: 0 + 79 = 79 2a + a2 = 79 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 = 79 + 1 Reorder the terms: 1 + 2a + a2 = 79 + 1 Combine like terms: 79 + 1 = 80 1 + 2a + a2 = 80 Factor a perfect square on the left side: (a + 1)(a + 1) = 80 Calculate the square root of the right side: 8.94427191 Break this problem into two subproblems by setting (a + 1) equal to 8.94427191 and -8.94427191.Subproblem 1
a + 1 = 8.94427191 Simplifying a + 1 = 8.94427191 Reorder the terms: 1 + a = 8.94427191 Solving 1 + a = 8.94427191 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + a = 8.94427191 + -1 Combine like terms: 1 + -1 = 0 0 + a = 8.94427191 + -1 a = 8.94427191 + -1 Combine like terms: 8.94427191 + -1 = 7.94427191 a = 7.94427191 Simplifying a = 7.94427191Subproblem 2
a + 1 = -8.94427191 Simplifying a + 1 = -8.94427191 Reorder the terms: 1 + a = -8.94427191 Solving 1 + a = -8.94427191 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + a = -8.94427191 + -1 Combine like terms: 1 + -1 = 0 0 + a = -8.94427191 + -1 a = -8.94427191 + -1 Combine like terms: -8.94427191 + -1 = -9.94427191 a = -9.94427191 Simplifying a = -9.94427191Solution
The solution to the problem is based on the solutions from the subproblems. a = {7.94427191, -9.94427191}
