Simplifying 8a2 + 3a + -800 = 0 Reorder the terms: -800 + 3a + 8a2 = 0 Solving -800 + 3a + 8a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -100 + 0.375a + a2 = 0 Move the constant term to the right: Add '100' to each side of the equation. -100 + 0.375a + 100 + a2 = 0 + 100 Reorder the terms: -100 + 100 + 0.375a + a2 = 0 + 100 Combine like terms: -100 + 100 = 0 0 + 0.375a + a2 = 0 + 100 0.375a + a2 = 0 + 100 Combine like terms: 0 + 100 = 100 0.375a + a2 = 100 The a term is 0.375a. Take half its coefficient (0.1875). Square it (0.03515625) and add it to both sides. Add '0.03515625' to each side of the equation. 0.375a + 0.03515625 + a2 = 100 + 0.03515625 Reorder the terms: 0.03515625 + 0.375a + a2 = 100 + 0.03515625 Combine like terms: 100 + 0.03515625 = 100.03515625 0.03515625 + 0.375a + a2 = 100.03515625 Factor a perfect square on the left side: (a + 0.1875)(a + 0.1875) = 100.03515625 Calculate the square root of the right side: 10.001757658 Break this problem into two subproblems by setting (a + 0.1875) equal to 10.001757658 and -10.001757658.Subproblem 1
a + 0.1875 = 10.001757658 Simplifying a + 0.1875 = 10.001757658 Reorder the terms: 0.1875 + a = 10.001757658 Solving 0.1875 + a = 10.001757658 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-0.1875' to each side of the equation. 0.1875 + -0.1875 + a = 10.001757658 + -0.1875 Combine like terms: 0.1875 + -0.1875 = 0.0000 0.0000 + a = 10.001757658 + -0.1875 a = 10.001757658 + -0.1875 Combine like terms: 10.001757658 + -0.1875 = 9.814257658 a = 9.814257658 Simplifying a = 9.814257658Subproblem 2
a + 0.1875 = -10.001757658 Simplifying a + 0.1875 = -10.001757658 Reorder the terms: 0.1875 + a = -10.001757658 Solving 0.1875 + a = -10.001757658 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-0.1875' to each side of the equation. 0.1875 + -0.1875 + a = -10.001757658 + -0.1875 Combine like terms: 0.1875 + -0.1875 = 0.0000 0.0000 + a = -10.001757658 + -0.1875 a = -10.001757658 + -0.1875 Combine like terms: -10.001757658 + -0.1875 = -10.189257658 a = -10.189257658 Simplifying a = -10.189257658Solution
The solution to the problem is based on the solutions from the subproblems. a = {9.814257658, -10.189257658}
