Simplify.<br> 2u? - 20u +42<br> u² – 5u+6

chubhunter [2.5K]

Answer:

The simplified expression is:

$\frac{2(u + 7)}{(u- 2)}$

Step-by-step explanation:

We want to simplify:

$\frac{2 {u}^{2} - 20u + 42}{ {u}^{2} - 5u + 6}$

We factor the numerator and the denominator to get:

$\frac{2(u - 3)(u + 7)}{(u- 2)(u- 3)}$

Cancel out u-2 which is common to the numerator and the denominator yo get:

$\frac{2(u + 7)}{(u- 2)}$
