Simplifying a2 + 17a + -1 = 0 Reorder the terms: -1 + 17a + a2 = 0 Solving -1 + 17a + a2 = 0 Solving for variable 'a'. Begin completing the square. Move the constant term to the right: Add '1' to each side of the equation. -1 + 17a + 1 + a2 = 0 + 1 Reorder the terms: -1 + 1 + 17a + a2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 17a + a2 = 0 + 1 17a + a2 = 0 + 1 Combine like terms: 0 + 1 = 1 17a + a2 = 1 The a term is 17a. Take half its coefficient (8.5). Square it (72.25) and add it to both sides. Add '72.25' to each side of the equation. 17a + 72.25 + a2 = 1 + 72.25 Reorder the terms: 72.25 + 17a + a2 = 1 + 72.25 Combine like terms: 1 + 72.25 = 73.25 72.25 + 17a + a2 = 73.25 Factor a perfect square on the left side: (a + 8.5)(a + 8.5) = 73.25 Calculate the square root of the right side: 8.558621384 Break this problem into two subproblems by setting (a + 8.5) equal to 8.558621384 and -8.558621384.Subproblem 1
a + 8.5 = 8.558621384 Simplifying a + 8.5 = 8.558621384 Reorder the terms: 8.5 + a = 8.558621384 Solving 8.5 + a = 8.558621384 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-8.5' to each side of the equation. 8.5 + -8.5 + a = 8.558621384 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + a = 8.558621384 + -8.5 a = 8.558621384 + -8.5 Combine like terms: 8.558621384 + -8.5 = 0.058621384 a = 0.058621384 Simplifying a = 0.058621384Subproblem 2
a + 8.5 = -8.558621384 Simplifying a + 8.5 = -8.558621384 Reorder the terms: 8.5 + a = -8.558621384 Solving 8.5 + a = -8.558621384 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-8.5' to each side of the equation. 8.5 + -8.5 + a = -8.558621384 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + a = -8.558621384 + -8.5 a = -8.558621384 + -8.5 Combine like terms: -8.558621384 + -8.5 = -17.058621384 a = -17.058621384 Simplifying a = -17.058621384Solution
The solution to the problem is based on the solutions from the subproblems. a = {0.058621384, -17.058621384}
