Where possible find all angles between 0 and 2(pi) that satisy the equation?

cot^2(theta)+5 = 6cot(theta)

Present your answer in radians

I got theta = (pi)/4 radians and 3.927 radians.

Is this correct or are there other solutions?

Apologies for poor formatting. Unsure how to do otherwise. Theta = angle.

Many thanks
