Factor.
49-4u?
what is the final answer?

(7 + 2√u)(7 - 2√u)

Step-by-step explanation:

There are two terms here, 49 and -4u.  These terms have nothing in common, so any factors will not be rational unless u is a positive perfect square.

However, we could rewrite 49 - 4u as 7^2 - [2√u]^2, which is the difference of two squares.  This latter result can be factored as

(7 + 2√u)(7 - 2√u)

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope
