There are no rational and real factors.

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

Is it possible to factor y=x^2+8x+20 y=x^2+8x+20 ? If so, what are the factors?
