Question

help please!! Find the zeroes of y = x(x − 4)(x + 2)

Answer 1

Just set all of them to 0
x = 0
x-4= 0 x = 4
x+2 = 0 x = -2
x's are 0,4,-2

Answer 2

help?

Answer 3

To find zero's of any x's you just have to set them all of them to 0 so you have 3 x's in that equation
x (x-4) (x+2) so you set them all equal to 0 to find where the zeros exist thus you get
x = 0
x-4=0
x+2=0
then you solve for x
first one is already done
x=0
second one
x=4
third one
x=-2 get it?

Answer 4

yes thanks
