Whats the question?
Sorry but can't answer if theres no question
The answer should be A. If you need work I can show you.
The vertex form:
The axis of symetry is x = h.
We have
Substitute:
<h3>Answer: x = -3</h3>
You would take out a 4x out of both terms because this is a common factor
4x^3-36x
4x(x^2-9)
and then you would notice that (x^2-9) is a difference of squares, so that factors out too
4x(x-3)(x+3)
that is all you can factor! hope this helps
First we expand the brackets:
-2a + 8 + 6a = 36
4a + 8 = 36
We then need to get the a's onto one side and the numbers onto the other:
4a = 28
We can then divide to get an x by itself:
a = 28/4 = 7
