Would it be possible to grade your video problems at the beginning? For instance: elementary level, or middle school, or high school, or college level? This one was a bit too advanced for me.

Looking at it, it’s a 345 . Tile setters and other construction people use that everyday.

The equation is the equation of a circle with radius sqrt(25)=5, so the polar form is r=5.

EDIT: I'm just wondering why you didn't take the square root of both sides of the equation you derived. Negative r has no physical meaning, so r=5 is easier to use than r^2=25.

That is defnitely not polar form, should be 5[45]
