Tan x tan x + tan x = 0

Step-by-step explanation:

We express the angle x in radians for all possible values of x:

let tan(x)=u:

#Substitute back u=tan(x)

#We assign for all values of x

#Hence, the equation's solutions are:

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
