so the answer will be 9
The rejection region is give by

where the test statistics is given by

i.e.

Thus,

Using the statistical table, the level of the test is 0.04.
The factored form of this expression is (x+3)(x-3)(x-6)
<h3>Factored form of an expression</h3>
Given the polynomial function
x^3-6x^2-9x+54
Group
(x^3-6x^2)-(9x+54)
Factor out the greatest common factor
x^2(x-6) - 9(x- 6)
Find the factors
(x^2-9)(x-6)
using the difference of two square
(x+3)(x-3)(x-6)
Hence the factored form of this expression is (x+3)(x-3)(x-6)
