Factoring requires you to reduce as much as possible. To factor 7x + 49, you remove the common factor of 7x and 49, which is 7, and multiply (7x + 49)/7 (which is x + 7) by 7, without actually simplifying.
7x + 49 = 7(x + 7)
Then, if possible, do the same thing until it cannot be further factored.

(x + 7)(x2 - 7x + 49)
7x(3x3 - 2x2 + 5x + 1)
It is: 7(x+2y)
6x2 + 7x - 5 = (3x + 5)(2x - 1)
49x2 - 84x + 36 = (7x - 6)(7x - 6) or (7x - 6)2
