Simplifying 2a2 = -6 + 8a Solving 2a2 = -6 + 8a Solving for variable 'a'. Reorder the terms: 6 + -8a + 2a2 = -6 + 8a + 6 + -8a Reorder the terms: 6 + -8a + 2a2 = -6 + 6 + 8a + -8a Combine like terms: -6 + 6 = 0 6 + -8a + 2a2 = 0 + 8a + -8a 6 + -8a + 2a2 = 8a + -8a Combine like terms: 8a + -8a = 0 6 + -8a + 2a2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(3 + -4a + a2) = 0 Factor a trinomial. 2((1 + -1a)(3 + -1a)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(1 + -1a)' equal to zero and attempt to solve: Simplifying 1 + -1a = 0 Solving 1 + -1a = 0 Move all terms containing a to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1a = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1a = 0 + -1 -1a = 0 + -1 Combine like terms: 0 + -1 = -1 -1a = -1 Divide each side by '-1'. a = 1 Simplifying a = 1Subproblem 2
Set the factor '(3 + -1a)' equal to zero and attempt to solve: Simplifying 3 + -1a = 0 Solving 3 + -1a = 0 Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -1a = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1a = 0 + -3 -1a = 0 + -3 Combine like terms: 0 + -3 = -3 -1a = -3 Divide each side by '-1'. a = 3 Simplifying a = 3Solution
a = {1, 3}
