Answer 2

(6x - 7) (6x - 7)

Explanation:

A perfect square trinomial will be in the form of
`a^2` ±
`2ab + b^2.` A trick to factoring a perfect square trinomial would to write it as
`(a^2`±
`b^2)`. (When doing this, the sign in the middle is determined by the middle sign in the original trinomial).

`36x^2 -84x + 49` is known as a perfect square trinomial, too. Its first and last terms are both perfect squares (6x squared makes
`36x^2`, 7 squared makes 49) and the middle term is 2 times the square roots of both of the other terms (
`(2) (7) (6x)` is
`84x`).

So, we can use the trick described earlier, and the answer would be
`(6x-7)^2`, also known as (6x-7) (6x-7).
