How do you factor the expression #2x^2+ 5x + 3#?

Suggest using the quadratic formula here (altho' other methods would work):

a = 2; b = 5; c = 3.

                -5 plus or minus sqrt( 25-4(2)(3) )
Then x =
                                      2(2)
                 -5 plus or minus sqrt (1)           -5 plus or minus 1
            = =
                                   4                                          4

-1 is one root, so x+1 is one factor.  Can you find the other root and factor?
