Simplifying -1a2 + -7a + 2 = 0 Reorder the terms: 2 + -7a + -1a2 = 0 Solving 2 + -7a + -1a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -2 + 7a + a2 = 0 Move the constant term to the right: Add '2' to each side of the equation. -2 + 7a + 2 + a2 = 0 + 2 Reorder the terms: -2 + 2 + 7a + a2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 7a + a2 = 0 + 2 7a + a2 = 0 + 2 Combine like terms: 0 + 2 = 2 7a + a2 = 2 The a term is 7a. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7a + 12.25 + a2 = 2 + 12.25 Reorder the terms: 12.25 + 7a + a2 = 2 + 12.25 Combine like terms: 2 + 12.25 = 14.25 12.25 + 7a + a2 = 14.25 Factor a perfect square on the left side: (a + 3.5)(a + 3.5) = 14.25 Calculate the square root of the right side: 3.774917218 Break this problem into two subproblems by setting (a + 3.5) equal to 3.774917218 and -3.774917218.Subproblem 1
a + 3.5 = 3.774917218 Simplifying a + 3.5 = 3.774917218 Reorder the terms: 3.5 + a = 3.774917218 Solving 3.5 + a = 3.774917218 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + a = 3.774917218 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + a = 3.774917218 + -3.5 a = 3.774917218 + -3.5 Combine like terms: 3.774917218 + -3.5 = 0.274917218 a = 0.274917218 Simplifying a = 0.274917218Subproblem 2
a + 3.5 = -3.774917218 Simplifying a + 3.5 = -3.774917218 Reorder the terms: 3.5 + a = -3.774917218 Solving 3.5 + a = -3.774917218 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + a = -3.774917218 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + a = -3.774917218 + -3.5 a = -3.774917218 + -3.5 Combine like terms: -3.774917218 + -3.5 = -7.274917218 a = -7.274917218 Simplifying a = -7.274917218Solution
The solution to the problem is based on the solutions from the subproblems. a = {0.274917218, -7.274917218}
