Which polynomial is represented by the algebra tiles? 2x2 – 4x – 6 2x2 4x 6 –2x2 – 4x – 6 –2x2 4x 6.
natta225 [31]

Polynomials consist of both indeterminates and coefficients. The polynomial that is been represented by the algebra tiles is 2x²-4x -6.

<h3>What are polynomials?</h3>

A polynomial consists of both indeterminates and coefficients and involves mathematical operations such as addition, subtraction, multiplication, and division.

In order to find the polynomial that is been represented by the tiles, we will simply, calculate the number of tiles for each variable,

As we can see in the image,

Number of tiles labeled as x² = 2

Number of tiles labeled as -x = 4

Number of tiles labeled '-' = 6

therefore, the polynomial can be written as 2x²-4x -6.

Hence, the polynomial that is been represented by the algebra tiles is 2x²-4x -6.
