Subproblem 1

Set the factor '(-12 + -1a + 2a2)' equal to zero and attempt to solve: Simplifying -12 + -1a + 2a2 = 0 Solving -12 + -1a + 2a2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -6 + -0.5a + a2 = 0 Move the constant term to the right: Add '6' to each side of the equation. -6 + -0.5a + 6 + a2 = 0 + 6 Reorder the terms: -6 + 6 + -0.5a + a2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + -0.5a + a2 = 0 + 6 -0.5a + a2 = 0 + 6 Combine like terms: 0 + 6 = 6 -0.5a + a2 = 6 The a term is -0.5a. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5a + 0.0625 + a2 = 6 + 0.0625 Reorder the terms: 0.0625 + -0.5a + a2 = 6 + 0.0625 Combine like terms: 6 + 0.0625 = 6.0625 0.0625 + -0.5a + a2 = 6.0625 Factor a perfect square on the left side: (a + -0.25)(a + -0.25) = 6.0625 Calculate the square root of the right side: 2.46221445 Break this problem into two subproblems by setting (a + -0.25) equal to 2.46221445 and -2.46221445.
