F(x)+g(x) = (x+7) + (x-3) =
x + 7 + x - 3 =
2x + 4

F -6*-6 = 36 which is a positive interger
The formula for the discriminant is b^2-4ac. The formula you wote is in the form of
ax^2+c=0, so first, you need to bring that -2 to the left. When you do that, you get (the original equation would be ax^2+bx+c but you have no bx.)
3x^2-8
So, since there's no b, it would be
b^2-4ac
0^2-4(3)(-8
-12 x -8
96
