Simplifying a2 = -16 + -10a Solving a2 = -16 + -10a Solving for variable 'a'. Reorder the terms: 16 + 10a + a2 = -16 + -10a + 16 + 10a Reorder the terms: 16 + 10a + a2 = -16 + 16 + -10a + 10a Combine like terms: -16 + 16 = 0 16 + 10a + a2 = 0 + -10a + 10a 16 + 10a + a2 = -10a + 10a Combine like terms: -10a + 10a = 0 16 + 10a + a2 = 0 Factor a trinomial. (8 + a)(2 + a) = 0Subproblem 1
Set the factor '(8 + a)' equal to zero and attempt to solve: Simplifying 8 + a = 0 Solving 8 + a = 0 Move all terms containing a to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + a = 0 + -8 Combine like terms: 8 + -8 = 0 0 + a = 0 + -8 a = 0 + -8 Combine like terms: 0 + -8 = -8 a = -8 Simplifying a = -8Subproblem 2
Set the factor '(2 + a)' equal to zero and attempt to solve: Simplifying 2 + a = 0 Solving 2 + a = 0 Move all terms containing a to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + a = 0 + -2 Combine like terms: 2 + -2 = 0 0 + a = 0 + -2 a = 0 + -2 Combine like terms: 0 + -2 = -2 a = -2 Simplifying a = -2Solution
a = {-8, -2}
