Jenna constructs the model to represent 3x2 + 11x – 4.

An algebra tile configuration. 0 tiles are in the Factor 1 spot. 0 tiles are in the Factor 2 spot. 20 tiles are in the Product spot in 4 columns with 5 rows. First row: 3 + x squared, 1 negative x. The last 4 rows are the same: 3 + x, 1 negative.
What factors does Jenna need to model for the sides?

(3x + 1) and (x – 4)
(3x – 1) and (x + 4)
(3x – 2) and (x + 2)
(3x + 2) and (x – 2)

(3x − 1) and (x + 4)

Check: (3x − 1)(x + 4) = 3x^2 + 12x − x − 4 = 3x^2 + 11x − 4, which matches.
