x^2 - y^2=49
the form of the circle is:
(x−h)2 + (y−k)2 = r2
Since we don't have h and k, their values are 0. r^2 = 49, and sqrt49 = 7
So, if we take the square root of the terms in the equation, we get:
x - h + y - k = 7 and this, 7, is the radius of your circle.
The center of the circle is found at (h,k) = (0, 0)

Equation of a circle: 

How and when, in this universe that we live, will y2 be NEGATIVE.

Do you actually know anything about math, ADDINGUP....SIMPLE MATH? Obviously NOT!!

I wonder when you people will stop leading these students astray. 

If you're not familiar with the topic or don't know what you're doing, then leave the problem alone, so someone who knows what they're doing can respond with a sensible answer.
