Question 422050: I'm homeschooled and I can't seem to get the steps of this problem.
The question is:
Which statement describes the graph of the equation x^2 + y^2 + 4x - 6y - 3 = 0
The answer is:
A circle with center (-2, 3) and radius 4.
I'm unsure how to get that answer.

Complete the square:

Constant term to the RHS:

Group like variables:

Divide the first degree x term coefficient by 2, square the result, and add that result to both sides:

Repeat for the first degree y term:

Factor the two perfect square trinomials in the LHS and collect terms in the RHS.

The equation of a circle with center at and radius is:

So re-write your equation:
