Answer:

There are no rational and real factors.

Explanation:

The expression#x^2 +8x+20# does not have real and rational factors.
There are no factors of #+20# which ADD to give #8#

However, the expression #x^2 +8x -20# has two factors:

#(x+10)(x-2)#

The factors #10 and -2# are factors of#-20# can be added to give 8
