Question

simplificati fractiile:$\frac{2x+6}{5x+10}$ = ?????
$\frac{3x-6}{2x-4}$=????? $\frac{ x^{2} +2x+1}{ x^{2} -1}$=?????? $\frac{ x^{2} -4}{ x^{2} -4x+4}$=?????

Answer 1

2(x+3)/5(x+2) nu se poate simplifica,sigur ai greșit scrierea
3(x-2)/2(x-2)=3/2
(x+1)(x+1)/(x-1)(x+1)=x+1/x-1
(x-2)(x+2)/(x-2)(x-2)=x+2/x-2

Answer 2

Ai rezolvarea in atașament !
