The Answers are

Step-by-step explanation:
Let we Know some Identities
cosec (-θ) = - cosec (θ)
    sec (-θ) = sec (θ)
     cot (-θ) = - cot (θ)
Also,

Therefore,

 
        
             
        
        
        
Add 2 to both sdies
now if we can facor, then if 
xy=0 then x and/or y=0
note:xy=x times y and x(y) =x times y
x^2+3x+2=0
what 2 number multiply to get 2 and add to get 3
the numbers are 2 and 1
(x+2)(x+1)=0
set them to zero
x+2=0
subtract 2
x=-2
x+1=0
subtract 1
x=-1
x could be -1 or -2
x=-2, or -1
