For problems 4 7 perform the indicated operation and reduce the answer to lowest terms. For problems 1 3 reduce each of the following to lowest terms. Divide and express as a simplified rational state the domain so we start off with this expression we actually have one rational expression divided by another rational expression and like weve seen multiple times before these rational expressions arent defined when the denominators are equal to zero so P plus 5 cannot be equal to 0 if we subtract both.
Well the same is true for rational expressions. That is Ill switch from dividing by a fraction to. To divide a fraction by another fraction we multiply the first fraction by the reciprocal of the second fraction.
So when dealing with rational expressions we will always assume that whatever x is it wont give division by zero. Change the division sign to a multiplication sign and flip or reciprocate the fraction after the division sign. By using this website you agree to our Cookie Policy.
