Answer 1

Hii

you are welcome in my ans

(x^2 + 1)(x^2 +2)/(x^2 +3)(x^2 +4)

let x^2 = t

(t +1)(t +2)/(t+3)(t+4) =y

(t^2 + 3t+ 2)/t^2 +7t +12 = y/1

using corponendo and dividando

2(t^2 + 5t + 7) / -2(2t+5)=( y + 1)/(y-1)

(t^2 + 5t +7 / -2t -5) +1 =( y + 1)/(y -1) + 1

t^2 + 3t + 2 / -2t -5= y/ y - 1

your solution is attached above ........
