How do you write the equation #x^2 + y^2 – x + 2y + 1 = 0# into standard form?
Now, complete the square for each variable.
Don't forget to balance both sides of the equation. (If you add something to one side, add it to the other side as well.)
This is in the standard form of a circle
Thus, this is a circle with a center at
Here's a graph. (Notice the center at
