Question 760602
The equation 2tan^2x+10 tanx+12 can be factored. It's solutions are tan x=-2 and tan x=-3. How many solutions of tan x=-2 exist on the interval 0=x=2pi. This i really Urgent, so thank you in advance
----------------
If tanx = -2 x is an angle in QII or x is an angle in QIV.
---
In QII the answer is tan^-1(-2) = 2.0344 radians
In QIV the answer is tan^-1(-2) = 3.1416 radians
