Hello :
<span>cot (2 θ) + cot ( θ) = 0
</span>cot (2 θ) = - cot ( θ)
cot (2 θ) = cot ( - θ)
2 θ = - θ +2k <span>π k in : Z
</span>θ = 2k π /3
in : <span>[0, 2π)
</span>k=0 : θ = 0
k=1 : θ = 2π /3
k=2 : θ = 4π /3

The solutions for 
is option 3. 
Step-by-step explanation:
Step 1:
First, we must bring the equation to the form of 
So becomes 
The value of a is the coefficient of the 
term, the value of b is the coefficient of x term and c is the coefficient of the constant term.
Comparing the above equation to 
we get 
and 
We have the formula 
Step 2:
By substituting the known values, we get
This is the third option.
