1. Please can someone explain how to solve this, my brain is dead

tan^2x + root3 tanx = 0

Values of x 0<_ x <_ 360

Could I factorise by tan x?

2. You tell me. Can you take out tanx as a common factor? What happens when you do?

Tanx(tanx + root3) = 0 ?

tanx + root3 = 0

tanx = -root3

X= 120 and 300?

Please tell me if I'm wrong.
