+230 The equation $x^2-kx-12=0$ has only integer solutions for certain positive integers $k$. What is the sum of all such values of $k$?
+37156 Factors of -12 that when added = positive k (note that k has a negative sign in front of it in the equation)
1 -12 added together = k = (-) 11
2 -6 (-) 4
3 - 4 (-) 1
example : (x+1)(x-12) = x^2 -11x -12 k = 11
11 + 4 + 1 = 16
