You can put this solution on YOUR website! 1.) If the roots of the quadratic equation x(sq)+bx+24=0 are integers, find the possible values of b.
----------------
x^2 + bx + 24 = 0
Integer roots have to be factors of 24.
eg, 1 & 24 --> (x-1)*(x-24) = 0 --> b = -25
2 & 12 --> (x-2)*(x-12) = 0 --> b = -14
-2 & -12 --> (x+2)*(x+12) = 0 --> b = +14
etc
