Question

what are the x-intercepts of y=-2(x-7)(x+2)?

Answer 1

you might want to solve
-2(x-7)(x+2) first then set x = 0 to solve for y

Answer 2

and then?

Answer 3

then whatever the answer will be your y-intercept
y-intercept means the value(s) that inherently touches the y-axis because x=0

Answer 4

isn't she asking for the x-intercepts nin

Answer 5

how do you set it to zero?

Answer 6

not y = 0
y-intercept is when x= 0 shamil
ohhhhhh nvm

Answer 7

I thought I read y-intercept <.<

Answer 8

-2(x-7)(x+2) = y
set y = 0
-2(x-7)(x+2) = 0
and solve for x, to get ur intercepts

Answer 9

let me rephrase then

Answer 10

the answers are -7 and 2
7 and -2
14 and -4
14 and -2

Answer 11

so i dont think you set it to zero

Answer 12

so if you're looking for the x-intercept then set your y to zero then solve
since your equation is already in factored form, solve it like this
x-7 = 0 and x+2 = 0, the -2 outside is automatically zero

Answer 13

so then its 7, -2
you do opposite the signs?

Answer 14

x-7 = 0
x - 7 + 7 = 0 + 7
x= ?

x+2 = 0
x+ 2 + (-2) = 0 + (-2)
x = ?

Answer 15

-2(x-7)(x+2) = 0
divide by -2 to both sides
(x-7)(x+2) = 0
x = 7 , x= -2

Answer 16

ooo I get it thank you!
