Help on this trig eqn: (tan x + 1) (2sin x + squr root 3)= 0

[rjm546]

I need help on this problem (tan x + 1) (2sin x + squr root 3)= 0

When I solved this equation my answers are x= pi/3, 2pi/3, 3pi/4, 7pi/4)

My question about this is I let tan x + 1= 0 and 2sin x + sq root 3= 0 and got those answers but doesnt the equation have to be the same trig functions?
