For this case we have the following polynomial:
![5b-15c](https://img.qammunity.org/2019/formulas/mathematics/high-school/aq8wvodwvrg89r6298mmia80neb9sgaj08.png)
The first thing we must observe is the most repeated factor.
We observe that this factor is 5.
We can do common factor 5 to rewrite the polynomial.
We then have to rewrite:
Answer:
The rewritten polynomial is given by:
![5 (b-3c)](https://img.qammunity.org/2019/formulas/mathematics/high-school/i5zbtpr1ja4y4exedctvf55ej1teau6y8o.png)
