Question

Rezolvati:
E(x)= (1 supra x-1 - 1 supra x+1) impartita la 1 supra x patrat -1    Aici se termina ecuatia

E(x)=(x+1 supra x - x supra x+1) impartit la 9x partat -1 supra 3x patrat + x 
Aici se termina ecuatia


E(X)= (x supra x+4- 2x+3 supra x-4 - x patrat + 10x-8 supra 16- x patrat) impartit la 10 supra 3x-12
 Aici se termina ecuatia

Answer 1

E(x)¹=>x+1-(x-1)/(x-1)•(x+1) •(x²-1)=>
=>x+1-x+1/(x-1)•(x+1) •(x-1)•(x+1)=>
=>2.

E(x)²=>2x+1/3x²+2x-1

E(x)³=>-3x⁴-39x³+87x²-288x-48/-19x³-30x²-160
