Simplifying a2 + 7a = 9 Reorder the terms: 7a + a2 = 9 Solving 7a + a2 = 9 Solving for variable 'a'. Reorder the terms: -9 + 7a + a2 = 9 + -9 Combine like terms: 9 + -9 = 0 -9 + 7a + a2 = 0 Begin completing the square. Move the constant term to the right: Add '9' to each side of the equation. -9 + 7a + 9 + a2 = 0 + 9 Reorder the terms: -9 + 9 + 7a + a2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + 7a + a2 = 0 + 9 7a + a2 = 0 + 9 Combine like terms: 0 + 9 = 9 7a + a2 = 9 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 = 9 + 12.25 Reorder the terms: 12.25 + 7a + a2 = 9 + 12.25 Combine like terms: 9 + 12.25 = 21.25 12.25 + 7a + a2 = 21.25 Factor a perfect square on the left side: (a + 3.5)(a + 3.5) = 21.25 Calculate the square root of the right side: 4.609772229 Break this problem into two subproblems by setting (a + 3.5) equal to 4.609772229 and -4.609772229.Subproblem 1
a + 3.5 = 4.609772229 Simplifying a + 3.5 = 4.609772229 Reorder the terms: 3.5 + a = 4.609772229 Solving 3.5 + a = 4.609772229 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 = 4.609772229 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + a = 4.609772229 + -3.5 a = 4.609772229 + -3.5 Combine like terms: 4.609772229 + -3.5 = 1.109772229 a = 1.109772229 Simplifying a = 1.109772229Subproblem 2
a + 3.5 = -4.609772229 Simplifying a + 3.5 = -4.609772229 Reorder the terms: 3.5 + a = -4.609772229 Solving 3.5 + a = -4.609772229 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 = -4.609772229 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + a = -4.609772229 + -3.5 a = -4.609772229 + -3.5 Combine like terms: -4.609772229 + -3.5 = -8.109772229 a = -8.109772229 Simplifying a = -8.109772229Solution
The solution to the problem is based on the solutions from the subproblems. a = {1.109772229, -8.109772229}
