Good morning forum I need some assistance with the following question:
Put the equation x2 + y2 + 8x + 2y = 29 into standard form and sketch the graph of the equation.
Thanks AC

I take it that the 2's are superscript.
So it should read .
First off, this is the equation of a circle.
The standard form of a circle is where h is the x-coordinate of the centre, k is the y-coordinate of the centre, and r is the radius.
To get it into this standard form, complete the square on the x terms and the y terms.
.
So what's the centre? What's the radius? Can you sketch the circle?
