SOLUTION: Find all solutions to the equation: 2sin^2x + 3sinx + 1=0??
This is how I attempted to solve the problem.
Replace sin with x
2x^2 +3x+1=0
Then I used "flower power"

Question 721004: Find all solutions to the equation: 2sin^2x + 3sinx + 1=0??
This is how I attempted to solve the problem.
Replace sin with x
2x^2 +3x+1=0
Then I used "flower power"
Borrow x
x^2+3x+2=0
Then u simply
(sin+1)(sin+2)=0
sin+1=0. sin+2=0
sin= -1. sin=-2
