Question

FIE POLINOAMELE P(X)=X2-2X-1,Q(x)=X-2 a)CALCULATI P (1)
b)determinari restul impartirii polinomului P(X)LA Q(x) c)aflati radacinele polinomului P(X)

Answer 1

P(1)=1 patrat -2*1-1= -2
P(X) LA Q(X):
P(2)=2 patrat-2*2-1=-1

Answer 2

P(1)=1-2-1=-2
b)P(2)=4-4-1=-1
c)P(x)=0⇒Δ=4+4=8
x1=2-√8)/2
x2=(2+√8)/2
