and notice that both terms are square numbers.
and
.
There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares
, it can always be factored into
.
Here, we can apply that. In this case, a = 7x and b = 3. So:
![49x^2-9=(7x)^2-3^2=(7x+3)(7x-3)](https://tex.z-dn.net/?f=49x%5E2-9%3D%287x%29%5E2-3%5E2%3D%287x%2B3%29%287x-3%29)
Thus, the answer is A.
Hope this helps!
