(x-19)(x+1)....k=18
(5x+7)^2 k=70
(25x+7)(x+7) k=181, or
(25x-7)(x-7) k=-181
(5x+49)(5x+1) k=150 or -150
(25x+49)(x+1) k=74 or -74
(25x+1)(x+49) k=1275 or -1275
For each of the following expressions, determine all of the values of k that allow the trinomial to be factored over the integers.
A) x^2 + kx - 19
B) 25x^2 + kx + 49
C) x^2 + kx + 8
