Question

1/40 Descompuneti in fatori:
a) 4x-8=?
b) 16a²-9b²=?
c) x²+3x+2=?
3/40 Aratati ca (x-2)·(x+2)·(x²+4)·(x⁴ +16)·(x⁸ + 256)=x¹⁶-2¹⁶
5/40 Aratati ca numarul a=(x-1)·(x+4)+x+8 este patrat perfect,oricare ar fi numarul intreg x.
6/40 Se considera numarul x∈R*.Daca x+1 supra x=3,calculati x²+1 supra x².

DAU PUNCTE + COROANA!!!
