To find the x intercepts, we need to put the standard form equation into factored form.
Which two numbers multiply to -8 and add to -2?


So the factored form is

That means the x intercepts are at 
So now we have the x intercepts.
To find the vertex, we need to convert the standard form equation into vertex form.
The formula of vertex form is 
Since the a value in the standard form equation is 1, the a value in vertex form is also one.
The h value can be found using the formula 
Which comes out to
or 1.
To find the k value, we can just plug in what we got for h back into the equation.

So the vertex is
.
This also means the axis of symmetry is 
Finally, to find the y intercept, we plug in 0 for x and solve.

So the y intercept is
.
Answer:
-2
Step-by-step explanation:
Since we are adding 3 to the x-coordinate and subtracting 1 from the y-coordinate, (-5, 2) becomes (-2, 1).
If you provide more information then I could try to help :)
Answer:

Step-by-step explanation:
First, we need to isolate
by taking it common from both terms on the right:

Now, since we want
in terms of the other variables, we can divide the left hand side (A) by whatever is multiplied with
on the right hand side. Then we will have an expression for
. Shown below:

This is the xpression for
