help please :)

Question

Reduce these complex fractions as much as possible (solve all please):

 

A)  3  -  4 

    2x   5x  

   1 - 2

   3   x

 

B)    1    - 3

     x-2           

      5    + 3

    x+2

 

C) Divide 3x³+2x²-4x+2 by x-1

 

D) Divide 4x³-2x by x+2

Answer 1

A)

    3-4= -1

     2x  5x    =10x^2

     1-2= -1

      3 x =3x

 

  B)

      1-3  = -2

       x-2  = x-2

        5 +3   =8

        x+2  = x+2

 

 

The answers for division are computer generated

 

P(x)=3x3+2x2−4x+2Q(x)=x−1

P(x) divided by Q(x) is:

P(x)Q(x)=3x2+5x+1

with the remainder of 3 .

 

 

 

 

P(x)=4x3−2x

Q(x)=x+2

P(x) divided by Q(x) is:

P(x)Q(x)=4x2−8x+14

with the remainder of −28
