Simplifying 12a2 + 9a + -13 = 0 Reorder the terms: -13 + 9a + 12a2 = 0 Solving -13 + 9a + 12a2 = 0 Solving for variable 'a'. Begin completing the square. Divide all terms by 12 the coefficient of the squared term: Divide each side by '12'. -1.083333333 + 0.75a + a2 = 0 Move the constant term to the right: Add '1.083333333' to each side of the equation. -1.083333333 + 0.75a + 1.083333333 + a2 = 0 + 1.083333333 Reorder the terms: -1.083333333 + 1.083333333 + 0.75a + a2 = 0 + 1.083333333 Combine like terms: -1.083333333 + 1.083333333 = 0.000000000 0.000000000 + 0.75a + a2 = 0 + 1.083333333 0.75a + a2 = 0 + 1.083333333 Combine like terms: 0 + 1.083333333 = 1.083333333 0.75a + a2 = 1.083333333 The a term is 0.75a. Take half its coefficient (0.375). Square it (0.140625) and add it to both sides. Add '0.140625' to each side of the equation. 0.75a + 0.140625 + a2 = 1.083333333 + 0.140625 Reorder the terms: 0.140625 + 0.75a + a2 = 1.083333333 + 0.140625 Combine like terms: 1.083333333 + 0.140625 = 1.223958333 0.140625 + 0.75a + a2 = 1.223958333 Factor a perfect square on the left side: (a + 0.375)(a + 0.375) = 1.223958333 Calculate the square root of the right side: 1.106326504 Break this problem into two subproblems by setting (a + 0.375) equal to 1.106326504 and -1.106326504.Subproblem 1
a + 0.375 = 1.106326504 Simplifying a + 0.375 = 1.106326504 Reorder the terms: 0.375 + a = 1.106326504 Solving 0.375 + a = 1.106326504 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-0.375' to each side of the equation. 0.375 + -0.375 + a = 1.106326504 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + a = 1.106326504 + -0.375 a = 1.106326504 + -0.375 Combine like terms: 1.106326504 + -0.375 = 0.731326504 a = 0.731326504 Simplifying a = 0.731326504Subproblem 2
a + 0.375 = -1.106326504 Simplifying a + 0.375 = -1.106326504 Reorder the terms: 0.375 + a = -1.106326504 Solving 0.375 + a = -1.106326504 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-0.375' to each side of the equation. 0.375 + -0.375 + a = -1.106326504 + -0.375 Combine like terms: 0.375 + -0.375 = 0.000 0.000 + a = -1.106326504 + -0.375 a = -1.106326504 + -0.375 Combine like terms: -1.106326504 + -0.375 = -1.481326504 a = -1.481326504 Simplifying a = -1.481326504Solution
