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

@ranga

Answer 2

If p and q are the roots, then the quadratic equation will be: y = a(x - p)(x - q)

Here p = -6 and q = 2. Substitute in the above equation.
You can find a knowing that the vertex lies on the curve. So put x = -2, y = -16 and solve for a.

Answer 3

what about q

Answer 4

Oops i see

Answer 5

@ranga a equals 1

Answer 6

yes.

Answer 7

Thats right!?

Answer 8

y = x2 + 4x −1

Answer 9

yes a = 1. The equations is: y = x^2 + 4x - 12

Answer 10

the one goes there like that

Answer 11

The equations is: y = x^2 + 4x - 12 so the answer is 12?

Answer 12

yes.

Answer 13

I thought u said the answer was 1

Answer 14

No, the value of "a" = 1. With a = 1, y = a(x - p)(x - q) becomes
y = (x + 6)(x - 2) = x^2 + 4x - 12
And the blank in the answer is 12.

Answer 15

OHHH Thanks so much btw is that you in the picture

Answer 16

yes and two dogs.

Answer 17

I love the picture I didn't even notice the dogs the lol
