Question

Factor tanˆ2(x)-3 tan(x)+2=0

Answer 1

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

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
