Respuesta :

D is the correct formula that the model represents. Black represents negative values, while white represents positive. 

The polynomial -x² + x -2 represents the given model.

What is a polynomial?

'A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.'

According to the given problem,

The big black square represents -x²

The two white rectangles represent 2x

The black rectangle represents -x

The small white square is 1

The three black squares are -1-1-1 = -3

After adding up the equation gets to,

-x² + x - 2

Hence, we can conclude that -x²+x-2 is the polynomial that represents the given model.
