Question

Yun was trying to factor 7x^2-14x7x

Answer 1

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 :

⇒ $Area = length(width)$  .........(1)

Now , According to question we have

⇒ $Area = 7x^2-14x$

⇒ $Area = 7x(x-2)$

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

⇒ $width = 7x$ or , $width =x -2$

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

Answer 2

49x
