c?

jimthompson5910 (jim_thompson5910):

let z = csc(x) that allows us to replace every copy of "csc(x)" with z giving us this expression: 2z^2 - 3z - 5

jimthompson5910 (jim_thompson5910):

factor 2z^2 - 3z - 5

OpenStudy (anonymous):

(2z-5)(z+1)

OpenStudy (anonymous):

@jim_thompson5910

OpenStudy (anonymous):

the answer will be 2csc-5

OpenStudy (anonymous):

well 2cscx - 5
