Chapter 7: Q. 80 (page 667)

In the following exercises, add.
$\frac{3 s^{2}}{3 s - 2} + \frac{13 s - 10}{3 s - 2}$

Short Answer

Expert verified

The simplified expression is $s + 5$ but $s \neq \frac{2}{3}$ .

Step by step solution

Step 1. Given Information

The given expression is $\frac{3 s^{2}}{3 s - 2} + \frac{13 s - 10}{3 s - 2}$ .

Step 2. Add the numerator

As the denominator is the same for both the terms, add the numerator and place it over the common denominator.

$\frac{3 s^{2}}{3 s - 2} + \frac{13 s - 10}{3 s - 2} = \frac{3 s^{2} + 13 s - 10}{3 s - 2}$

Step 3. Factor the numerator

Factor the expression in the numerator and then cancel out the common terms from the numerator and denominator.

$\frac{(3 s - 2) (s + 5)}{(3 s - 2)} = s + 5$

So, the resultant expression is $s + 5$ but the denominator of the given expression was $3 s - 2$ , so, $s \neq \frac{2}{3}$ .
