So the equation is this:
9sec2θtanθ−12tanθ=0
And somehow it factors out to this:
3tanθ(3sec2θ−4)=0
Can someone explain to me the factoring steps? I'm very lost Thanks! P.S. I hate pearson my math lab with a burning passion
9sec^2 (x) tan(x) - 12tan (x) = 0 re-write as
9tan (x) sec^2 (x) - 12 tan (x) = 0
Factor out the greatest common factor, 3tan(x)
3tan (x) [ 3 sec^2 (x) - 4 ] = 0
Ohhh duh, thanks so much :)
