13-6.

Factor each of the following expressions.

Remember that a difference of two squares has a special factoring pattern.

Use the same method as part (a).

This might look different than the expressions in parts (a) and (b), but you can use the same method to factor it.

sin ^{2}Think of sin² (

) as one big variable (like).

Then use the same method as part (c) to factor it.
