Question

cos^2 theta + cos theta = 2 cos theta

Thank you!

Answer 1

\[\cos^2(\theta)+\cos(\theta)=2\cos(\theta)\]
Do you want to find theta? First combine the like terms
\[\cos^2(\theta)-\cos(\theta)=0\]
After this it can be easily solved by factoring

Answer 2

thats the thing lol.... i dont factor tan sin and cos very well:)
