Chapter 8: Q. 282 (page 966)

In the following exercises, simplify.
$\frac{\frac{3}{s + 6} + \frac{5}{s - 6}}{\frac{1}{s^{2} - 36} + \frac{4}{s + 6}}$

Short Answer

Expert verified

The simplified expression is $\frac{8 s + 12}{4 s - 23}$

Step by step solution

Step 1. Given information

The given expression is

$\frac{\frac{3}{s + 6} + \frac{5}{s - 6}}{\frac{1}{s^{2} - 36} + \frac{4}{s + 6}}$

Step 2. Simplify the expression

$\frac{\frac{3}{s + 6} + \frac{5}{s - 6}}{\frac{1}{s^{2} - 36} + \frac{4}{s + 6}} = \frac{(s + 6) (s - 6) (\frac{3}{s + 6} + \frac{5}{(s - 6)})}{(s + 6) (s - 6) (\frac{1}{(s + 6) (s - 6)} + \frac{4}{s + 6})} = \frac{3 (s - 6) + 5 (s + 6)}{1 + 4 (s - 6)} = \frac{8 s + 12}{4 s - 23}$

The simplified expression isrole="math" localid="1647792054607" $\frac{8 s + 12}{4 s - 23}$

Step 3. The solution

The simplified solution is $\frac{8 s + 12}{4 s - 23}$
