I could really use your help on a couple of problems that I'm having trouble on...

Question

Simplify each rational expression. Write answers with excluded values.

1.) 6d^2c/3c

 

4.) x^2-x/(x-1)(x+7)

 

Multiple. Write answers with excluded values.

 

2.)4/3a^2bc*6bc/8w

 

3.)(w-9)(w-3)/(w+2)(w+1)*(w+2)(w-11)/(w-9)(w-11)

 

(don't worry only two left...sorry for all of these...)

 

Divide. Write answers with excluded values.

 

5.)14k^3v/v^2-4÷7ky^4/v^2+4v+4

 

9.)(d-3)(d^2+3d+9)/d+1÷d(d-3)/(d-9)(d+1)

 

Again, I'm sorry for asking help on so many...you don't have to explain how you got your answers, I'll figure that out myself.

Answer 1

A "couple" is two. You submit 6.

If you can "figure it out" yourself, why ask the questions?
