Question

tell me the answer Pease I don't know ​

Answer 1

here is your answer mate:

= (4x/x^2-1) - [(x+1)/(x-1)]

= by cross multiplying we get,

= [ 4x(x-1) ] - [ (x+1)(x^2-1) ]

= [ 4x^2 - 4x ] - [ x^3 - x + x^2 - 1 ]

= by opening the brackets we get,

= 4x^2 - 4x - x^3 + x - x^2 + 1

= - x^3 + 4x^2 - x^2 - 4x + x + 1

= - x^3 + 3x^2 - 3x + 1

hope this answer helps you buddy
