Question

Solve: tan(x)(tan x+1)=0.

Please explain. Thank you!

Answer 1

you have 2 functions tan x and tan x + 1 which when multiplied equal 0
this means that either tan x = 0 or tan x + 1 = 0
so you need to solve these 2 equations

Answer 2

So I need to solve for x?

Answer 3

for tan x = 0 would x be pi?

Answer 4

well x = 0 and then followed by multiples of pi
