Al resolver las operaciones para los polinomios proporcionados resulta:
A)f(x) + g(x) =2x^2+ 4x - 2
B)f(x) - h(x) = 2x^2+ x - 1 -3/(x-2)
C)g(x) + h(x) - i(x) = 3x – 1+ 3/(x-2)- (x+1)/(x+2)
D)h(x) . i(x)= 3(x+1)/(x²-4)
E)f(x) . i(x) = (2x^2+ x - 1) *(x+1)/(x+2)
F)h(x) + g(x) =3/(x-2) + 3x – 1
G)h(x) - i(x) = 3/(x-2) - (x+1)/(x+2)
H)i(x) + g(x) = (x+1)/(x+2)+3x – 1
Para los polinomios :
f(x)= 2x^2+ x - 1 ; g(x)= 3x – 1 ; h(x)= 3/(x-2) ; i(x)= (x+1)/(x+2)
A)f(x) + g(x) = 2x^2+ x - 1 + 3x – 1 = 2x^2+ 4x - 2
B)f(x) - h(x) =( 2x^2+ x - 1) -(3/(x-2) )= 2x^2+ x - 1 -3/(x-2)
C)g(x) + h(x) - i(x) = 3x – 1+ 3/(x-2)- (x+1)/(x+2)
D)h(x) . i(x)= 3/(x-2) * (x+1)/(x+2)= 3(x+1)/(x²-4)
E)f(x) . i(x) = (2x^2+ x - 1) *(x+1)/(x+2)
F)h(x) + g(x) =3/(x-2) + 3x – 1
G)h(x) - i(x) = 3/(x-2) - (x+1)/(x+2)
H)i(x) + g(x) = (x+1)/(x+2)+3x – 1
