Chapter 11: Q16. (page 699)

Find the product.
$\frac{m}{m^{2} + 3 m + 2} . \frac{m + 2}{m^{2}}$

Short Answer

Expert verified

The final answer is $\frac{1}{m (m + 1)}$ .

Step by step solution

Step 1. Define a rational function.

A function of the form $y = \frac{p}{q}$ is called a rational function, where $p$ and $q$ are the polynomials and $q \neq 0$ .

Step 2. Define the product of two expressions ab and cd.

The product of two expressions $\frac{a}{b}$ and $\frac{c}{d}$ , where $b \neq 0$ and $d \neq 0$ , is given below.

$\frac{a}{b} . \frac{c}{d} = \frac{a c}{b d} ........... (1)$

Step 3. Calculate the product mm2+3m+2.m+2m2.

Use $(1)$ to find the product $\frac{m}{m^{2} + 3 m + 2} . \frac{m + 2}{m^{2}}$ .

$\begin{matrix} \frac{m}{m^{2} + 3 m + 2} . \frac{m + 2}{m^{2}} = \frac{m (m + 2)}{(m^{2} + 3 m + 2) (m^{2})} \\ = \frac{m + 2}{m (m^{2} + 3 m + 2)} \\ = \frac{m + 2}{m (m^{2} + 2 m + m + 2)} \\ = \frac{m + 2}{m (m (m + 2) + 1 (m + 2))} \\ = \frac{m + 2}{m (m + 2) (m + 1)} \\ = \frac{1}{m (m + 1)} \end{matrix}$

Therefore, the final answer is $\frac{1}{m (m + 1)}$ .
