Factor the expression completely.

7x - x2

x(7 - x)

Step-by-step explanation:

Given

7x - x² ← factor out x from both terms

= x(7 - x) ← in factored form

If the vertex of a parabola is given, you can begin with this general equation:
(h,k) is the vertex
So given (2,2) is the vertex that can be substituted into the equation.
You also stated the parent formula is . This means a = 2.5.
I simply substituted the values into the general equation.
If you perform all possible operations, an alternative equation is
