Answer:

x^2 - 9x + 20

Step-by-step explanation:

(x - 4)(x - 5) (have to do the opposite for it to be positive)

FOIL method: X x X = x^2

-5 x X = -5x

-4 x X = -4x

x^2 - 5x - 4x + 20

-5 - 4 = -9 so...

x^2 - 9x +20 is the answer

Note:
A polynomial of order n is of the form
$f(x)=a_{n}x^{n}+a_{n-1}x^{n-1} + \, ..., \, +a_{1}x+a_{0}$
where the a's are constants.

Consider the given expressions.
x/5 + 2 Not a polynomial
35x² It is a polynomial of order 2
7x⁷ - x⁵ It is a polynomial of order 7
4x + √(x-1) It is not a polynomial

Answer:
