Answer:
(x - 9)(x + 4)
Step-by-step explanation:
x^2−5x−36
As you know, -36 = -9 * 4 and (-9) + 4 = -5
so Factor
= (x - 9)(x + 4)
Answer:
D. is the answer I got i think it is right but IDK
Um I have no idea what this is but good luck
Answer: Option D

Step-by-step explanation:
For a quadratic function of the form

The x coordinate of the vertice is:

In this case the function is:

So

The x coordinate of the vertice is:

The y coordinate of the vertice is:

The vertice is: (-3, -11)
The form e vertice for a quadratic equation is:

Where
the x coordinate of the vertice is h and the y coordinate of the vertice is k.
Then h=-3 and k =-11
Finally the equation
in vertex form is:
