The model represents a polynomial and its factors.


Which equation is represented by the model?

x2 – 2x – 3 = (x – 3)(x + 1)
x2 – 4x + 3 = (x – 3)(x – 1)
x2 + 2x + 3 = (x + 3)(x – 1)
x2 + 4x – 3 = (x + 3)(x + 1)

So first, you want to go through each answer choice and try out the factors.
A.)
x^2-2x-3=(x-3)(x+1)
Use FOIL method.
First:  (x)(x)=x^2
Outside: x(1)=x
Inside: -3(x)=-3x
Last:  -3(1)=-3

You should end up with:
x^2+x-3x-3

Which then simplified is:
x^2-2x-3

So your answer is A.

The equation that is represented by the model is A. x² – 2x – 3 = (x – 3)(x + 1)

How to calculate the value?

From the information given, the FOIL method can be utilized in this scenario.

After the completion of this, the equation will be:

= x² + x -3x - 3

Collect like terms

= x² + x - 3x - 3

= x² - 2x - 3
