Answer:
C. (x + 4)(x + 5).
Step-by-step explanation:
We need 2 numbers whose product is + 20 and whose sum is + 9.
They are + 5 and + 4 , so
x2 + 9x +20
= (x + 4)(x + 5).
Assuming that their exam success is independent then
P(both fail) = 1/4 x 2/5 = 2/20 or 1/10
and
. So we have a remainder of

and
. Subtracting this from the previous remainder gives a new remainder

and
. Subtracting this from the previous remainder gives a new one of

and we're done since 2 does not divide
. So we have
