Answer 1

a.)

 

W(x)+P(x)

x^4+x^2+x+x^5+x^2= x+2x^2+x^4+x^5

 

W(x)-P(x)

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

 

b.)

 

W(x)+P(x)

3/4x^6-2x^4+5/4x^2+4+1/4x^6+2x^4+x^3-1/4x^2-2x+2= x^6+x^3+x^2-2x+6

 

W(x)-P(x)

3/4x^6-2x^4+5/4x^2+4-1/4x^6-2x^4-x^3+1/4x^2+2x-2=1/2x^6-4x^4-x^3+3/2x^2+2x+2

 

 

 

 

 

 

Answer 2

a) W(x)+P(x)= x^4+x^2+x+x^5+x^2= x^5+x^4+2x^2+x

     W(x)-P(x)=x^4+x^2+x-x^5-x^2=-x^5=x^4+x

 

b) W(x)+P(x)=-3/4x^6-2x^4+5/4x^2+4+1/4x^6+2x^4+x^3-1/4X^2-2x+2=

                     =-1/2x^6+x^3+x^2+6

 

W(x)-P(x)=-3/4x^6-2x^4+5/4x^2+4-1/4x^6-2x^4-x^3+1/4X^2+2x-2=

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