Answer:
(x+2)(x+8)

Explanation:

1) First, we need to see which number multiplies to 16 and adds up to 10.

By looking at the factors of 16, we can see that only 2 and 8 will work.

2) Now, we need to arrange them in the factorized equation, which is always

(x+r)(x+q).

3) This will give us our final equation:


(x+2)(x+8)

If you want the roots, just do the negation of r and q and you will get it!
