Writing: suppose your friend was absent today how would you explain to your friend how to add and subtract rational expressions?
Answer: when the expressions have like denominators add or subtract numerators as indicated and place over the denominator when they have unlike denominator factor if needed, find the LCD rewrite expressions with the same denominator add or subtract as indicated and simplify

Compare and contrast: How is finding the LCD of two rational expressions similar to finding the LCD of two numerical fractions? How is it different?
Answer: the procedure for finding LCD and LCM both are similar the LCD is LCM of the denominator After finding LCM use LCM as the LCD. both are same whenever both denominators are different, first find LCM of denominator if it require use LCM has LCD.

Reasoning: your friend says she can always find a common denominator for two rational expressions by finding the product of the denominator
a Is your friend correct? Explain.
b Will your friend’s method always give you the LCD? ExpIain
Answer:
a Yes. finding LCD after converting both denominators is same.
b NO. it will give you a common denominator but necessary the least common denominator when the denominator is same my friend method correct when ever different denominator my friend method wrong

Compare and contrast
Whenever dividing polynomial by monomial, j can multiply by the reciprocal of the divisor and then simplifying it is easy to calculate by division method will get same answer but reciprocal method is easy to find the answer I prefer reciprocal method and both methods are same .by using both will get same answer

Writing: when you use the LCD to add or subtract rational expressions will the answer always be in simplest form if you use the LCD? Explain
Answer: Not always may some time
Whenever using LCD after simplification the numerator may contain a factor of LCD, in that case simplest form is possible, all the time it is not possible.
