The discriminant of equation ax^2+bx+c = 0 is b^2-4ac.

Here b = 12, a = -4, c = -9 so discriminatn is

b^2-4ac = 12^2-4(-4)(-9) = 144 - 144 = 0.

The discrimant is 0. This tells us that there is only 1 x-intercept for this quadratic

The given parabola is $y+4=12(x-7)^2$ . Compare with the standard equation of a parabola in vertex form, $y-c=a(x-b)^2$ .

The vertex of this parabola is $(b,c)$ . Compare $y+4=12(x-7)^2$ with the standard equation $y-c=a(x-b)^2$ .

we see $c=-4,b=7$ . Thus, the vertex of the given parabola is $(7,-4)$ .
