Hope this helps u. I’m more than welcome to help u!!! :)
I think it would be .0123
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
