Is x^4-1 a factor of P(x)=x^5+5x^4-x-5? If it is, write P(x) as a product of two factors. This confuses the heck out of meh. pls hlep fast!!!

x^5+ 5x^4 -x - 5     let's factor this....so we have

 

x^4 ( x + 5) - 1 ( x + 5)      the common factor is  x + 5.....so.....

 

( x +5) ( x^4 - 1)   

 

And that is writing the original polynomial as a product of two polynomial factors

 

 

cool cool cool
