What side lengths should be used to model the rectangle?

A rectangle with an area of x2 - 4x - 12 square units is

represented by the model.

(x + 2) and (x - 6)

(x + 6) and (x - 2)

(x + 2) and (x - 10)

(x + 10) and (x - 2)

(x+2) (x-6)

this is because when you cross multiplication of the given area, how you simplify x^2 will be x and x, for 12 it will be + 2 and - 6 = > (x+2) (x-6)

you can also use the quadratic formula, if you use the quadratic formula, turn the negative value into (x + number) and positive into (x - number)
