The 5x5 square grid has 6 , 2 x 2 subgrids and the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12.

<h3>What is a Square ?</h3>

A square is a polygon with four sides and all the sides are equal and parallel and all the angle value is 90 degree.

(a) The 5x5 square grid has 6 , 2 x 2 subgrids.

(b) the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12

as it can be understood from the figure 2 that only the last square doesn't have a pair and the rest all does

more than that will be extra but 12 will be enough to make all the grey squares of 2 x 2 subgrid .

Answer:

The given expression is a cubic polynomial with degree 3.

Step-by-step explanation:

We are given the following in the question:

$3x^3-x^2$

Polynomial:

A polynomial is an expression.
It consisting of variables and coefficients.
The variables and coefficients involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

Since, the given expression satisfies all the properties, it is a polynomial.
