Question

A polynomial is factored using algebra tiles.

What are the factors of the polynomial?

A.(x − 1) and (x + 3)

B.(x + 1) and (x − 3)

C.(x − 2) and (x + 3)

D.(x + 2) and (x − 3)

Answer 1

NOOO the answer is B on EdgenA polynomial is factored using algebra tiles.

What are the factors of the polynomial?

(x − 1) and (x + 3)

(x + 1) and (x − 3)

(x − 2) and (x + 3)

(x + 2) and (x − 3)uity

Answer 2

B.(x + 1) and (x − 3)

Explanation:

The upper side of the tiles show the expression (x + 1), and the left side shows the expression (x - 3) (see figure attached). In both cases, you have to consider how many +x or -x are (one +x in one case and three -x in the other case). If you multiply the factors, you get:

(x + 1)*(x - 3) = x^2 - 3x + x - 3

which is the expression made by all the tiles.
