Please help! Medal and fan

A polynomial function can be written as (x - 2)(x - 3)(x + 5). What are the x-intercepts of the graph of this function? (2, 0), (3, 0), (-5, 0) (-2, 0), (-3, 0), (5, 0) (2, 0), (3, 0), (5, 0) (-2, 0), (-3, 0), (-5, 0)

OpenStudy (gahm8684):

i think is b

@JoannaBlackwelder

OpenStudy (joannablackwelder):

Close. It looks like a to me. 2-2 =0 for example.

OpenStudy (gahm8684):

what do you mean *-*

OpenStudy (joannablackwelder):

You need for each set of parentheses to be 0.

OpenStudy (gahm8684):

then what do i do

OpenStudy (joannablackwelder):

To find the x-intercepts.

OpenStudy (joannablackwelder):

Plug in 2 for the first x.

OpenStudy (gahm8684):

(2-2)=0

OpenStudy (joannablackwelder):

Since 2-2 equals zero, what ever the other 2 numbers turn out to be, 0 times anything is 0. So, the function is 0.

OpenStudy (joannablackwelder):

Where y is 0 is an x-intercept.

OpenStudy (gahm8684):

what do you mean?

OpenStudy (joannablackwelder):

y=(x-2)(x-3)(x+5)

OpenStudy (joannablackwelder):

That is the function.

OpenStudy (gahm8684):

yeah but then whats the answer i dont get it

OpenStudy (joannablackwelder):

The answer is the values that make each set of parentheses 0.

OpenStudy (joannablackwelder):

Or A

OpenStudy (gahm8684):

ohhhhh now i get it

OpenStudy (gahm8684):

thanks man

OpenStudy (gahm8684):
