\

The equation is $\"\"$ .

\

For a trinomial to be factorable as a perfect square, the first and last terms must be perfect squares and the middle term must be two times the square roots of the first and last terms.

\

1. Is the first term a perfect square? Yes, $\"\"$ .

\

2. Is the last term a perfect square? Yes, $\"\"$ .

\

3. Is the middle term to $\"\"$ ? Yes, $\"\"$ .

\

Since all three conditions are satisfied, $\"\"$ is a perfect square trinomial.
