same like last one let tan x =a then take out common factor
so quadratic equation again?

ye... but first you should find out common factor
\[\huge\rm 7a^3 -21 a = 0\] what is common factor ?
7 is a common factor
yes right and what else ?
7a(a^2-3)=0
yep right set both 7a and a^2 -3 equal to zero solve for a
a=0 and a=sqrt.3
yep that means tan x = 0 and tanx = sqrt{3} unit circle!
tan = sin /cos
so wait what would I look for
tanx = 0 and tan x =sqrt 3 this one z tricky you have to divide sin over cos to find out tan
