Simplifying (15a3) + -1(3a) = 0 Remove parenthesis around (3a) (15a3) + -1 * 3a = 0 Multiply -1 * 3 (15a3) + -3a = 0 Reorder the terms: -3a + (15a3) = 0 Solving -3a + (15a3) = 0 Solving for variable 'a'. Factor out the Greatest Common Factor (GCF), '3a'. 3a(-1 + (5a2)) = 0 Ignore the factor 3.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 '(-1 + (5a2))' equal to zero and attempt to solve: Simplifying -1 + (5a2) = 0 Solving -1 + (5a2) = 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 + (5a2) = 0 + 1 Combine like terms: -1 + 1 = 0 0 + (5a2) = 0 + 1 (5a2) = 0 + 1 Combine like terms: 0 + 1 = 1 (5a2) = 1 Divide each side by '5'. a2 = 0.2 Simplifying a2 = 0.2 Take the square root of each side: a = {-0.447213596, 0.447213596}Solution
a = {0, -0.447213596, 0.447213596}
