The polynomial 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 equal to ?    Yes, .

Since all three conditions are satisfied.

Therefore, the polynomial is a perfect square trinomial.

Perfect square trinomial formula: .

           (Write as perfect square trinomial form)

                                                      (Factors using the pattern)

Therefore, the perfect square form is .

The perfect square form is .
