What is the product of the rational expressions below? x-8/x+11*x+8/x-11

Problem:

Step-by-step explanation:

Writing as one fraction:

Now before we continue, notice both of your bottom and top are in the form of (a-b)(a+b) or (a+b)(a-b) which is the same format.

That is, we are multiplying conjugates on top and bottom.

When multiplying conjugates, all you have to do it first and last.

For example:

.

So your problem becomes this after the multiplication of conjugates:

Step-by-step explanation:

We are to find the product of the rational expression below:

We are to multiply these terms by taking the LCM to get:

Since the signs of all the terms are different so we cannot add them up.

2.   2 3/5.

3.   2 1/2.

step-by-step explanation:

6 - 3 2/5

= 6 -   17/5

= 30/5 - 17/5

= 13/5

= 2 3/5 (answer).

5 1/4 - 2 3/4

= 21/4 - 11/4

= 10/4

= 2 1/2 (answer).
