This is no mistake he is the one
In vertex form the value of the vertex is easily identified in the equation. I’m standard form the value of the x intercepts are evident.
2/3 * x +13 = 22
2/3x + 13 = 22
if u need to solve it then ....
=> 2/3x = 22 - 13
=> 2/3x = 9
=> 2x = 9*3 = 27
=> x = 27/2
Hope it helps !!!
For this case we have the following polynomials:

By subtracting both polynomials we have:

What we must do is subtract terms of the same degree.
We have then:
Answer:
will be a polynomial
