Question

2. Which rational expression should be added to

Answer 1

let we assume that rational number which should be added to x cube minus 1 / X square + 2 to get 3 x cube + 2 X square + 4 / X square + 2 be 'p'.

so P is equal to 2 x cube + 2 X square + 5 / X square + 2.

hope this answer helps you a lot then please give me a brilliant answer.

Answer 2

Solution :

Let y should be add to (x³-1)/(x²+2) to

get (3x³+2x²+4)/(x²+2)

(x³-1)/(x²+2) + y = (3x³+2x²+4)/(x²+2)

=> y = (3x³+2x²+4)/(x²+2) - (x³-1)/(x²+2)

=>y= [3x³+2x²+4-(x³-1)]/(x²+2)

=> y = ( 3x³+2x²+4-x³+1 )/(x²+2)

=> y = ( 2x³ + 2x² + 5 )/(x²+2)
