I need help with a discussion on two rational expressions. Remember to factor all polynomials completely.

4k² 12k + 9

4k

3w² + 36

2w 8

Explain what the meaning of domain is. Also, explain why a denominator cannot be zero.

Find the domain for each of your two rational expressions.

Write the domain of each rational expression in set notation (as demonstrated in the example).

Do both of your rational expressions have excluded values in their domains? If yes, explain why they are to be excluded from the domains. If no, explain why no exclusions are necessary.

Incorporate the following five math vocabulary words into your discussion. Use bold font to emphasize the words in your writing.; use them appropriately in sentences describing the math work.

Domain

Excluded value

Set

Factor
