Hey guys,

the task: For what integral values of k can 4x^2 + kx - 3 be factored?

My answer:

(4) (-3) = -12 Factors of 12= 1,12 2,6 and 3,4

So are the possible values for k = +11, +4 and +1 or all negative?

They should be positive right, because I am looking for k and the sign is positive in front of k.
