Question

help algebra 1.

Answer 1

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 2

So you know that the graph is equal to 0 at the points x=-6 and x=2. So you can just look at them like this:

x+6=0 and x-2=0 and multiply them together since what you've multiplied together will now have to be =0 when you plug in those x values.

(x+6)(x-2)=0

Now just foil them out to find your answer.

Answer 3

can you help cause I don't know how to foil it out

can any of you guys help

Answer 6

First outer inner Last

Answer 7

what can you explain how to do it

Answer 8

(x+2)(x+4)
First terms(x*x) +outer terms x*4+ Inner terms x*2 + Last Term 2*4
X^2 +4x+2x+8
x^2+6x+8
