Best ResponseYou've already chosen the best response.1I would use trial an error from calculator, you key the equation into your calculator, then substitute any number for x and see if its equal to zero, if that value of x equals to zero, then that is the factor of the polynomial

Best ResponseYou've already chosen the best response.1Ok, according to the trial an error, x=8 works, so, f(8)=15(8)^3119(8)^210(8)+16=0

Best ResponseYou've already chosen the best response.1Now, x=8, (x8) is a factor of that polynomial. then use this to find other factors, by long division.

Best ResponseYou've already chosen the best response.0okay, so I'm dividing 15x^3119x^210x+16 divided by x8?
