The equation of a circle is x2 + y2 + 6x + 4y + 10 = 1. what is this equation written in its standard form?

You need to complete the square in x and in y,



First, group the x-terms and the y-terms separately.



Move the 10 to the right side by subtracting 10 from both sides.



Now complete the square in x and in y.
The constant you need to add to complete each square is the square of half of the coefficient of the x or y term. Make sure to add the constants to both sides of the equation.

The answer is 10. and if you go by pemdas you would 1. multiplication 2. division 3. addition 4. subtraction

Ithink it is b and d
