Find the product of all constants t such that the quadratic x^2 + tx - 18 can be facgtored in the form (x + a)(x + b), where a and b are integers.

======================================


-18  =     

 

-18 *  1    ⇒     t  =  -17

18 * - 1      ⇒   t  =  17

9 *  -2     ⇒      t  =     7

-9 * 2      ⇒      t  =   -7

6 * -3     ⇒       t   =  3

-6 * 3     ⇒       t =   -3
