Simplifying 20a2 = 16 + -32a Solving 20a2 = 16 + -32a Solving for variable 'a'. Reorder the terms: -16 + 32a + 20a2 = 16 + -32a + -16 + 32a Reorder the terms: -16 + 32a + 20a2 = 16 + -16 + -32a + 32a Combine like terms: 16 + -16 = 0 -16 + 32a + 20a2 = 0 + -32a + 32a -16 + 32a + 20a2 = -32a + 32a Combine like terms: -32a + 32a = 0 -16 + 32a + 20a2 = 0 Factor out the Greatest Common Factor (GCF), '4'. 4(-4 + 8a + 5a2) = 0 Factor a trinomial. 4((-2 + -1a)(2 + -5a)) = 0 Ignore the factor 4.Subproblem 1
Set the factor '(-2 + -1a)' equal to zero and attempt to solve: Simplifying -2 + -1a = 0 Solving -2 + -1a = 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 + -1a = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -1a = 0 + 2 -1a = 0 + 2 Combine like terms: 0 + 2 = 2 -1a = 2 Divide each side by '-1'. a = -2 Simplifying a = -2Subproblem 2
Set the factor '(2 + -5a)' equal to zero and attempt to solve: Simplifying 2 + -5a = 0 Solving 2 + -5a = 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 + -5a = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -5a = 0 + -2 -5a = 0 + -2 Combine like terms: 0 + -2 = -2 -5a = -2 Divide each side by '-5'. a = 0.4 Simplifying a = 0.4Solution
a = {-2, 0.4}
