Factor out the gcf:


25f730f2=\displaystyle -{25}{f}^{{7}}-{30}{f}^{{2}}= (\displaystyle {(} )\displaystyle {)}

 
 

Note: When the leading term of a polynomial is negative, is usual practice to factor out a negative gcf. Remember that the "leading term" of a polynomial is the term of greatest degree. From this problem onward, always factor out a negative gcf if the leading term is negative.
