Simplifying 45a2 + 10a = 0 Reorder the terms: 10a + 45a2 = 0 Solving 10a + 45a2 = 0 Solving for variable 'a'. Factor out the Greatest Common Factor (GCF), '5a'. 5a(2 + 9a) = 0 Ignore the factor 5.Subproblem 1
Set the factor 'a' equal to zero and attempt to solve: Simplifying a = 0 Solving a = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a = 0Subproblem 2
Set the factor '(2 + 9a)' equal to zero and attempt to solve: Simplifying 2 + 9a = 0 Solving 2 + 9a = 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 + 9a = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 9a = 0 + -2 9a = 0 + -2 Combine like terms: 0 + -2 = -2 9a = -2 Divide each side by '9'. a = -0.2222222222 Simplifying a = -0.2222222222Solution
a = {0, -0.2222222222}
