What is the second question? Don’t seem to understand what you’re asking
But the first is
(2sinx-1)(Sinx-1)
Treat it the sinx as you would with normal factorising equations with x. If it helps you, you could always substitute the sinx as a U, and then change it back to sinx once you have factorised it
