Answer:

Because there is no common terms in them.

Step-by-step explanation:

Prime factors of 8x is 8, x

Prime factors of 3y is 3,y

Common factor=0

Hence,it cannot be factorised.

Answer:

Explain why 8x+3y cannot be factorized

Lets factor the constants in each term:

8 can be factored as (1 x 8) or (2 x 4).

3 is a prime number and therefore can only be factored to 1 and 3

Because there are no common factors other than 1 the constants cannot be factored.

There is no y in the first term (8x) and no x in the second term (3y)

Therefore this expression cannot be factored.
