Factor tanˆ2 (x) - 3 tan (x) + 2=0

(tan (x) - 2) (tan (x) - 1) = 0

Step-by-step explanation:

This is the same as a polynomial, you can factor the same way. To make it simpler you can substitute tan (x) for any random variable like u.

u^2 - 3u + 2 = 0 (factor)

(u-2) (u-1) = 0 (substitute u back for tan (x))

(tan (x) - 2) (tan (x) - 1) = 0
