Question

Answer 1

a: A(x)+B(x)+C(x)

=x^6-3x^4+2x^2-11+5x^6+4x^4-7x^2-6+C(x)

=6x^6+x^4-5x^2-5+2x^6-x^4+3x^2+5

=8x^6-2x^2

b: A(x)-B(x)-C(x)

=x^6-3x^4+2x^2-11-(5x^6+4x^4-7x^2-6+2x^6-x^4+3x^2+5)

=x^6-3x^4+2x^2-11-7x^6-3x^4+4x^2+1

=-6x^6-6x^4+6x^2-10

c: C(x)-B(x)-A(x)

=2x^6-x^4+3x^2+5-(6x^6+x^4-5x^2-5)

=2x^6-x^4+3x^2+5-6x^6-x^4+5x^2+5

=-4x^6-2x^4+8x^2+10
