PLEASE someone just help me, im desperate Identify the constant difference for a hyperbola with foci (−3, 0) and (3, 0) and a point on the hyperbola (7, 0).

Yo need to use discriminant
for ax²+bx+c=0the discriminat is b²-4ac
if the discriminant is1. less than 0, then 0 real solutions2. equal to 0, then 1 real solutions3. if more than 0, then 2 real solutions
given
6x²-2x+7=0a=6b=-2c=7(-2)²-4(6)(7)4-168we can see this is less than 0no real solutions
