Sorry, I'm new here. We are supposed to set the equation equal to zero to see what X equals within (0, 2pi)
I tried it two ways:
tan^2x-5tanx+5=0
(tanx-3)(tanx-2)=0
(tanx-3)=0 (tanx-2)=0
tanx=3 tanx=2
but then what? it doesn't seem to work out because in class the answer seemed to come out to be like tanx=sqrt. 3
then it the final answer would be pi/3 and 4pi/3.
My other method:
tan^2x-5tanx+5=0
tan^2x-5tanx=-5
tanx(tanx-5)=-5
but then I'm confused how i can set tanx=-5 or (tanx-5)=-5
Sorry for not reading the terms, will read them now!
