Answer:
2nd option
Step-by-step explanation:
Using the identities
tan²θ + 1 = sec²θ
cotθ = 
Given
secθ = - 
, then
tan²θ + 1 = (- )² = 
( subtract 1 from both sides )
tan²θ = 
( take the square root of both sides )
Since 
< θ < π and tanθ < 0 , then
tanθ = - 
Then
cotθ = 
= - 
Answer:
The discriminant is:
b
2
−
4
a
c
a
=
1
b
=
12
c
=
36
Substitute these values into the discriminant and you should get two answers (real roots):
12
2
−
4
(
1
)
(
36
)
=
0
If the discriminant is 0 there is 1 real root, if it is > 0 there are 2 and otherwise 0 real roots.
