For this case we have the following polynomial:
[tex]5b-15c
[/tex]
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:
[tex]5b-15c = 5 (b-3c)
[/tex]
Answer:
The rewritten polynomial is given by:
[tex]5 (b-3c)[/tex]
