Question

What are the zeros of the polynomial function: f(x) = x3 + 10x2 + 24x ?

–6, 0, 4

6, 0, –4

–6, 0, –4

6, 0, 4

Can someone please explain

Answer 1

i was thinking C?

Answer 2

first factor out an x from each term
\[x(x^2+10x+24)\]

then factor
x(x+4)(x+6)

now set everything equal to 0
x=0
x+4=0
x+6=0

and solve for x
x=0
x=-4
x=-6

Does that make sense?

Answer 3

yes

Answer 4

wait, still a little confused

Answer 5

is it C or D?
