Adi used algebra tiles to represent the product (negative 2 x minus 1)(2 x minus 1).

an algebra tile configuration. 4 tiles are in the factor 1 spot: 2 are labeled negative x and 2 are labeled negative. 3 tiles are in the factor 2 spot: 2 are labeled + x and 1 is labeled negative. 12 tiles are in the product spot: 4 are labeled negative x squared, 4 are labeled negative x, 2 are labeled + x, and 2 are labeled +.
which is true regarding adi’s use of algebra tiles?

she used the algebra tiles correctly.
she did not represent the two original factors correctly on the headers.
the signs on some of the products are incorrect.
some of the products do not show the correct powers of x.
