You mean this:
The constant terms in each binomial factor must give a product of -5. This combination would be either -1 and 5 OR 1 and -5.
The term 2x^2 would require terms of x to be 2x and x.
Check the different combinations of the terms in the binomials and the position of the terms.
(2x___-1)(x___5)
-
(2x___1)(x___-5)
-
(2x___-5)(x___1)
-
(2x____5)(x___-1)
WHICH one of those combinations works?
