we first have to find the factors of 7 and -3 and see which ones add up to -20.

factors of 7 are 1 and 7            factors of -3 are -1  and 3
                         7 and 1                                      -3 and 1

therefore, we get (x - 3) (7x + 1)

we can use the FOIL method to verify the answer.
