The factoring method which can be considered for such a cubic tetranomial expression is; factor by grouping sum of cubes.
<h3>What factoring method can be considered for the polynomial?</h3>
It follows from the task content that the order of the Polynomial is 3 and the polynomial is a tetranomial as it contains 4 terms.
On this note, since 3x³ is not a perfect cube, it follows that the best factorisation method for such a polynomial is; factor by grouping sum of cubes.

First, let's write down this inequality: 
<span>There are at least 245 students enrolled in the school.
 y≥245
This inequality says what the sentence says!
now, the number of teachers must be: 
x≥2*(y/25) 
 (two times the number of groups of students of 25!)
so those two inequalities, taken together will be the answer!
