Question

how many integer values of (a) can
x^2+ax+6 be factored?
What are they?

Answer 1

Think of factors of 6. you have 1,6; 2,3. The first gives you a=7; second gives you a=5. Then also include the negatives (-1,-6), etc. so -7 and -5 also. That gives you 4 possible a values.

hope this helps.
