Multiply both sides by a
(a + 4)a = -3
Regroup terms
a(a + 4) = -3
Expand
a^2 + 4a = -3
Move all terms to one side
a^a + 4a + 3 = 0
Factor a^2 + 4a + 3
(a + 1)(a + 3) = 0
Solve for a
<u>a = -1, -3</u>
Answer:
5x(f+9g)
Step-by-step explanation:

5(xf+9xg)
Consider xf+9xg. Factor out x.
x(f+9g)
Rewrite the complete factored expression.
5x(f+9g)
