Simplifying 21a2 + -49 = -28a Reorder the terms: -49 + 21a2 = -28a Solving -49 + 21a2 = -28a Solving for variable 'a'. Reorder the terms: -49 + 28a + 21a2 = -28a + 28a Combine like terms: -28a + 28a = 0 -49 + 28a + 21a2 = 0 Factor out the Greatest Common Factor (GCF), '7'. 7(-7 + 4a + 3a2) = 0 Factor a trinomial. 7((-7 + -3a)(1 + -1a)) = 0 Ignore the factor 7.Subproblem 1
Set the factor '(-7 + -3a)' equal to zero and attempt to solve: Simplifying -7 + -3a = 0 Solving -7 + -3a = 0 Move all terms containing a to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -3a = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -3a = 0 + 7 -3a = 0 + 7 Combine like terms: 0 + 7 = 7 -3a = 7 Divide each side by '-3'. a = -2.333333333 Simplifying a = -2.333333333Subproblem 2
Set the factor '(1 + -1a)' equal to zero and attempt to solve: Simplifying 1 + -1a = 0 Solving 1 + -1a = 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 + -1a = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1a = 0 + -1 -1a = 0 + -1 Combine like terms: 0 + -1 = -1 -1a = -1 Divide each side by '-1'. a = 1 Simplifying a = 1Solution
a = {-2.333333333, 1}
