What is this concept about?
This Concept goes over solving equations with half angle formulas. there will be a trig function within the equation that is a half angle, and in order to simplify the equation, you must substitute the half angle with the corresponding formula. (Unit S Concept 7)

What is Important to remember about this concept?
What is really important about this concept is to substitute the right formula in the equation. Also, in this problem in articular, it is important to realize that in order to solve for "x", you will need to do alot of substituting, and distribution. If you do not distribute correctly, you will not be able to use the Zero Product Property correctly. Remember to keep the equation set to zero when solving for "x".
