## Example Questions

### Example Question #11 : Expressions

Simplify the following rational expression: (9x - 2)/(x2) MINUS (6x - 8)/(x2)

Possible Answers:    Correct answer: Explanation:

Since both expressions have a common denominator, x2, we can just recopy the denominator and focus on the numerators. We get (9x - 2) - (6x - 8). We must distribute the negative sign over the 6x - 8 expression which gives us 9x - 2 - 6x + 8 ( -2 minus a -8 gives a +6 since a negative and negative make a positive). The numerator is therefore 3x + 6.

Simplify the following expression: Possible Answers:     Correct answer: Explanation:

Since both terms in the expression have the common denominator , combine the fractions and simplify the numerators:   ### Example Question #13 : Expressions

Simplify the following rational expression: Possible Answers:     Correct answer: Explanation:

Since both rational terms in the expression have the common denominator , combine the numerators and simplify like terms:    ### Example Question #281 : Algebra

Add and simplify: Possible Answers:     Correct answer: Explanation:

When adding rational expressions with common denominators, you simply need to add the like terms in the numerator.

Therefore, is the best answer.
