Respuesta:

Explicación paso a paso:

A(x)= X³-5X²+2X-3

B(x)= X³-X²-3X+2Y

C(x)= 1/2X+4X-1

a) A(x) + B(x)= X³-5X²+2X-3 +

X³-X²-3X+2Y

-----------------------

X³-6X²-X+2Y-3

b) A(x) - B(x)=

X³-5X²+2X-3 - (X³-X²-3X+2Y)

= X³-5X²+2X-3 -X³+X²+3X-2Y

= X³-X³-5X²+X²+2X+3X-2Y-

= -4X²+5X-2Y-3

c) B(x) - 4C(x)

= X³-X²-3X+2Y - 4(-X/2+4X-1)

= X³-X²-3X+2Y +4X/2-4X+1

= X³-X²-3X+2Y+2X-4X+1

= X³-X²-3X+2X-4X+2Y+1

= X³-X²-5X+2Y+1

d) 3A(x) - 2C(x)

=3(X³-5X²+2X-3) - 2(1/2X+4X-1)

=3X³-15X²+6X-9 - 2/2X-8X+1

=3X³-15X²+6X-X-8X-9+1

=3X³-15X²-3X-8
