What is the polar form of the equation (x+2)2+y2=4?

• r(r+4cosθ)=0
• r(r+4sinθ)=0
• r2=4rsinθ
• r2=4rcosθ

Question 2

What is the rectangular form of the polar equation $$θ={−5π\over6}$$?

$$y= \sqrt{3}x$$

$$y= {\sqrt{-3}\over 3} x$$

$$y={ \sqrt{3}\over 3}x$$

$$y= \sqrt{-3}x$$

For 2, can you show me how?
