Va rog dau coroanaaaaaaaaaaaa

Answer 1

Răspuns:

Explicație pas cu pas:

se descompun in factori

6x²+x-1=0

x1,2=-1±√1+24/12=-1±5/12      x1=1/3     x2=-1/2

6x²+x-1=(3x-1)(2x+1)

4x²+8x+3=0

x1,2=-4±√16-12/4=-4±2/4       x1=-1/2      x2=-3/2

4x²+8x+3=(2x+1)(2x+3)

F1(x)=(3x-1)(2x+1)/(2x+1)(2x+3)=(3x-1)/(2x+3)

⇒F1=F2
