Question

Find the zeros of the polynomial function with equation
f(x) = x3-x2 -30x

x = 0, x = 4, x = 5

x = 4, x = 5

x = -6, x = 5

x = 0, x = 6, x = -5

Answer 1

factor this first.
f(x)=x(x^2-x-30)
f(x)=x(x-6)(x+5)

Now solve each individual factor for zero to get the answers:
1. x=0
2. x-6=0
3. x+5=0

Answer 2

huh?

Answer 3

which part?

Answer 4

lol all of it..

Answer 5

What is a zero, in terms of the graph of the function?
