Please

First, do you know what zeroes of a function are?

OpenStudy (anonymous):

we just learned this and honestly no

OpenStudy (isaiah.feynman):

Oh, the zeroes are solutions to a polynomial, and on a graph they are points where y = 0. Which means they are on the x axis.

OpenStudy (anonymous):

oh ok

OpenStudy (anonymous):

ok i got that but im confused by number 2

OpenStudy (anonymous):

@ganeshie8

OpenStudy (wolf1728):

If the factors are x, x-2 and x+5 do you know the solutions (zeroes) of the equation?

OpenStudy (anonymous):

d. 1,11, and 111

OpenStudy (anonymous):

i i honestly have no idea how to do this

OpenStudy (wolf1728):

Quick lesson (x+4) * (x-5) = 0 What are the solutions (answers) (or zeroes) of that equation?

OpenStudy (anonymous):

-4 and 5

OpenStudy (anonymous):

i think

OpenStudy (wolf1728):

very good so if the factors of an equation are x, x-2, and x+5 then the solutions are?

OpenStudy (anonymous):

2 and -5

OpenStudy (anonymous):

so then the answer is B

OpenStudy (wolf1728):

and zero so looking at the 3 graphs, which one shows those values of x when y=0?

OpenStudy (anonymous):

B

OpenStudy (wolf1728):

the factors are x , x-2 and x+5 so the solutions are?

OpenStudy (anonymous):

2 and -5 so then the answer is B

OpenStudy (wolf1728):

There is a third solution

OpenStudy (anonymous):

oh and 0

OpenStudy (anonymous):

so its A

OpenStudy (wolf1728):

Very good , which makes the answer A :-)

OpenStudy (anonymous):

thank you

OpenStudy (wolf1728):

u r welcome
