Answer:
I think this is the solution
1. Write the factors
(x+3)(x-6) = 0
2. Multiply the factors to get the answer in standard form
x^2 + 3x - 6x - 18 = 0
3. Simplify
x^2 - 3x - 18 = 0
Step-by-step explanation:

<h3>Axis of symmetry is 0 and vertex is (0, -1)</h3>
<em><u>Solution:</u></em>
<em><u>Given is:</u></em>

We have to find the vertex and axis of symmetry
<em><u>The general equation is given as:</u></em>

Comparing with given equation,
a = 2
b = 0
c = -1
<em><u>The axis of symmetry is given as:</u></em>


Thus axis of symmetry is 0
The x coordinate of the vertex is the same
x coordinate of the vertex = 0
h = 0
The y coordinate of the vertex is:
k = f(h)
k = f(0)

Thus, y coordinate of the vertex is -1
Therefore, vertex is (0, -1)
Answer:
n=2
Step-by-step explanation:
Create an equation.
9n=18
Divide 9 from both sides.
9n/9=18/9
n=2
Hope this helps!
