The degree of a polynomial is the highest power of the polynomial.
The polynomial is 
The degree is given as:
The zero is given as:
Add 3 to both sides
From the question, we understand that the polynomial has a single zero.
So, the polynomial is:
Substitute 4 for n
Hence, the polynomial is

Answer:
x = 1 ±√89
Step-by-step explanation:
We have the equation:
(x+7)(x-9) = 25
Using distributive property:
x(x-9) + 7(x-9) = 25
x²- 9x + 7x - 63 -25 = 0
x²- 2x - 88 = 0
To complete squares we need to add and subtract 1, as follows:
x²- 2x - 88 +1 -1 = 0
x²- 2x +1 -88 -1 = 0 (this is a perfect square)
(x - 1)² - 89 = 0
Solving for x:
(x - 1)² = 89
x - 1 = ±√89
x = 1 ±√89
