Question

Va rog urgentttt oferr 60 de punctee tot exercitiul 21

Answer 1

a)=x(x²-4)=x(x-2)(x+2)
b)=a(x²-10²)=a(x-10)(x+10)
c)=x(x²+4x+4)=x(x+2)²
d)=x²-y²+a(2x+a)=(x-y)(x+y)+a(2x+a)
e)=(x-y)(x+y)+4(x+1)
f)=(x-y)(x+y)+a(2y-a)
g)=x⁴(x+1)-(x+1)=(x+1)(x⁴-1)=(x+1)(x²-1)(x²+1)
h)=x²(x+5)-3(x+5)=(x+5)(x²-3)
i)=x²(x-3)-9(x-3)=(x-3)(x²-9)
