Hint: first step, expand using (x+y)^(2) = x^(2)+2xy+y^(2)

When the 3 is factored out, the square also applies to it. (ab)\^2 = a\^2b\^2 not a(b\^2)

>if (3a + 3/a)^2 = 9
Take the square root of both sides:
3a+3/a=+/-3
Divide both sides by 3:
a+1/a=+/-1

(3a + 3/a)^2 = 9
(3a+3/a)(3a+3/a)=9
Divide both sides by 3:
(a+1/a))(3a+3/a)=3
