1. The problem statement, all variables and given/known data

Solve for θ.

2sinθcosθ + 1 - 2sin^2θ = 0

2. Relevant equations

No equations, just identities.

3. The attempt at a solution

I tried factoring, but I don't know how to continue with 2 diff ID's in one equation.

I don't know how to simplify it so that everything is in terms of one similar Identity.
