[College Trig] need help figuring out how we got here
I’m doing review for my exam today and have no clue how we went from:
sin squared theta plus 5 sin theta minus three
To
(2sin(x)-1)(sin(x)+3)
How did we do this??
I know she showed us this method using a giant x and something adds to something and something multiplied to something but I never learned that and I never grasped what to do.
Also if my solution is completely wrong then tell me.
