use the given zero to find the remaining zeros of the function
h(x)=x^415x^3+60x^2+70x816
zero: 5
show work

algebra 
Reiny,
if 5 is a zero, then x5 is a factor
So use either synthetic or long algebraic division to show that
x^415x^3+60x^2+70x816 = (x5)(....)
Hey, I just tried that and 5 is not a zero of your function, that is, x5 does not divide evenly.
