Show that x+2 is a factor of f(x)=x^4+2x^3−27x−54 . then factor f(x) completely.
f(x)=

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

in the attachment.   i didn't see your choices.   the word which means there is choices.
