A. Choose an example of a rationalexpression, and present a step by step solution.
B. Under what situation would one or more solutions of a rational equation be unacceptable?
C. Define a polynomial and a rationalexpression. What makes a rationalexpression unique? Provide two original examples of a rationalexpression an

Find the LCD for theexpressions below and convert each rationalexpression into an equivalent rationalexpression with the LCD as the denominator.
-3/ (2 p2 + 7p -15)
p/ (2 p2 - 11p +12)
2/ (p2 + p -20)
(See expression in Attachment)

For therationalexpression (x^2-1) / (x+1)^2, the domain of this is expression is?
all values of x
all values of x satisfying x does not equal 1
all values of x satisfying x does not equal -1
all values of x satisfying x does not equal 0
none of the above.

What is the range of a rationalexpression?
Be sure to limit your discussion to expressions only and keep in mind that functions, equations and graphs are not expressions. Give two examples of expressions and their respective range

In regards to the example that I included, can we cancel out the x's?
I guess the big question here is how to we identify whether we are dealing with factors or with terms?
Answer: When simplifying therationalexpression, it is improper to cancel out the x's in general. For instance, (x^2-x)/(x^2+x+1). We cannot cancel x

When simplifying therationalexpression, explain why it is improper to cancel out the x's? State a general rule for canceling factors in a rationalexpression and give an example of how this rule would be used. Use the following:
3a^2+5ab-2b^2/3a^2+8ab-3b^2.

(1) Explain how multiplying and dividing rationalexpressions is similar to multiplication and division of fractions. Give an example of each and compare the process.
