Chapter 6.6, Problem 101E

(a)

To determine

The value for which expression $P$ is undefined if $P,Q\text{ and }R$ are rational expressions and defined as follows: $P=\frac{6}{x+3},Q=\frac{5}{x+1}$ and $R=\frac{4x}{x^2+4x+3}$.

(b)

To determine

The value of for which the expression $Q$ is undefined if $P,Q\text{ and }R$ are rational expressions and defined as follows: $P=\frac{6}{x+3},Q=\frac{5}{x+1}$ and $R=\frac{4x}{x^2+4x+3}$.

(c)

To determine

The value for which the expression $R$ is undefined if $P,Q\text{ and }R$ are rational expressions and defined as follows: $P=\frac{6}{x+3},Q=\frac{5}{x+1}$ and $R=\frac{4x}{x^2+4x+3}$.
