Question

Determine the factors of x^2 − 7x − 10.

Answer 1

Are there two factors of -10 that have product -10 and sum -7?

Answer 2

5 2

Answer 3

Well ...

Answer 4

This is not factorable since -5(2)=-10 and -5+2=-3
and 5(-2)=-10 and 5+(-2)=3
You don't get -7
It is not factorable over the integers
