Question

Fill in the missing term so that the quadratic equation has a graph that opens up, with a vertex of (– 2, – 16), and x intercepts at x = -6 and x = 2. (Do not include the negative sign in your answer.) y = x2 + 4x − ___

Answer 1

write you x-intercepts in factored form and expand it.

Answer 2

Can you explain?

Answer 3

x intercepts at x = -6 and x = 2, right?
so factored form is y= (x-r)(x-s), where r= -6 and s= 2. plug it in then expand it..

Answer 4

y=(x--6)(x-2)

Answer 5

so it will be like this: y=(x+6)(x-2).. expand this

Answer 6

y=x^2-2x+6x-12

Answer 7

simplify

Answer 8

x^2+4x-12

Answer 9

there you go, you already have the answer.. just look at it and find the missing term:)

Answer 10

Can you explain to me what the answer is because im still not so sure @Data_LG2

Answer 11

y = x2 + 4x − ___.. compare this to your answer above.. the missing term will be ...

Answer 12

-12

Answer 13

?

Answer 14

@Data_LG2

Answer 15

kind of.. read your question again and it says: (Do not include the negative sign in your answer.) so the answer is?

Answer 16

12

Answer 17

Thank you so much!!!

Answer 18

a medal for you
