I believe the answer you are looking for is the quadratic formula. because it has the formula correct, and it to me just looks exactly like it.

So, it has the ax^2+bx+c=0 but just a little difference, it has a subtracting sign instead of adding.

I don't know if I am right, but that is my guess. I remember doing those lol

Which equation represents a circle centered at (3,5) and passing though the point (-2,9)
Maru [420]

The equation represents a circle centered at (3,5) and passing through the point (-2,9) will be,\rm x^2+y^2 -6x-10y-7=0

What exactly is a circle?

It is a point locus drawn equidistant from the center. The radius of the circle is the distance from the center to the circumference.

Given data;

The Centre of the circle is,(h,k)=(3,5)

The circle traverses (-2,9). Consequently, the radius of the circle r is equal to the separation between (3, 4) and (-2,1).

So radius;

r = \sqrt{{{(x_2-x_1)^2 + (y_2-y_1)^2}}

r = \sqrt{{(9-5)^2+(3+2)^2 }

r=\sqrt {41} \\\\ r =6.1 \ units

Now equation of the circle with center (h,k) and radius r is

\rm (x-h)^2 + (y-k)^2 = r^2\\\\ (x-3)^2 + (y-5)^2 = (\sqrt{41})^2\\\\ x^2 - 6x + 9 + y^2 - 10y + 25 = 41

x^2+y^2 -6x-10y-7=0

Hence equation represents a circle that will be,x^2+y^2 -6x-10y-7=0
