Question

how do you find all of the zeros of a function: ex f(x)=x^2(x+3)

Answer 1

To find the zeros of a function like the one you have, you set it equal to zero.

Answer 2

So, you have:
x^2(x+3) = 0

Answer 3

thank you so much

Answer 4

Then you set each equal to zero.

Answer 5

so you have x^2 = 0
x + 3 = 0

Answer 6

Can you solve those two?

Answer 7

x=3 or x=-3?

Answer 8

when you isolate your x, you subtract 3 on both sides.

Answer 9

x = 0 - 3
x = -3

Answer 10

But, you forgot the other equation.

Answer 11

x^2 = 0

Answer 12

you have to square root both sides.

Answer 13

so x can equal 3 and 0

Answer 14

so, your final answer:
x = -3 and x = 0

Answer 15

Those are your zeros.
Got it?

Answer 16

yes i get it thank you so much

Answer 17

No problem! :)
