Simplifying 21a2 + 57a + 30 = 0 Reorder the terms: 30 + 57a + 21a2 = 0 Solving 30 + 57a + 21a2 = 0 Solving for variable 'a'. Factor out the Greatest Common Factor (GCF), '3'. 3(10 + 19a + 7a2) = 0 Factor a trinomial. 3((2 + a)(5 + 7a)) = 0 Ignore the factor 3.Subproblem 1
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 = -2Subproblem 2
Set the factor '(5 + 7a)' equal to zero and attempt to solve: Simplifying 5 + 7a = 0 Solving 5 + 7a = 0 Move all terms containing a to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + 7a = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 7a = 0 + -5 7a = 0 + -5 Combine like terms: 0 + -5 = -5 7a = -5 Divide each side by '7'. a = -0.7142857143 Simplifying a = -0.7142857143Solution
a = {-2, -0.7142857143}
