Question 999894: f(x)= 〖2x〗^2-16x+30 ,
g(x)= 〖x(x-3)〗^2 〖(x+1)〗^4
Find the zeros of g(x)and f(x)

Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
f(x)=4x^2-16x+30
x=(1/8)(16+/- sqrt (256-480). The square root is negative. There are no zeros.

x(x-3)〗^2 〖(x+1)〗^4
Either of the two must equal zero
x=0, x=3, x=-1
