First of all this isn't correct. It should be

R = X squared + Y squared

r

Second, if you have a textbook, check it again, because there are at least two other equations that can be used to convert polar equations:

x = r cos θ and y = r sin θ.

As for your problem,

r = 2 cos θ,

start by multiplying both sides by r. Then substitute.
