2
−14x7, x, squared, minus, 14, x. He found that the greatest common factor of these terms was 7x7x7, x and made an area model:

What is the width of Yun's area model?

the width of Yun's area model is 7x units or ( x-2 )units .

Step-by-step explanation:

Here we have , Yun was trying to factor 7x^2-14x.  He found that the greatest common factor of these terms was 7x and made an area model:  What is the width of Yun's area model. Let's find out:

We know that area of rectangle :

⇒  .........(1)

Now , According to question we have

⇒

⇒

Comparing this equation to equation (1) we get that :

⇒ or ,

Therefore , the width of Yun's area model is 7x units or ( x-2 )units .
