How do you factor 4y² plus 28xy?

The greatest common factor in the two terms is [ 4y ].The factored form of the expression is4y (y + 7x)


How do you factor 7x 21 14y?

Look for the GCF. 7, 14 and 21 all have 7 as a common factor. Divide that out. 7x divided by 7 = x 21 divided by 7 = 3 14y divided by 7 = 2y 7x + 21 + 14y = 7(x + 3 + 2y)


Is 1x plus 13 the greatest common monomial factor of 7x 91?

If you mean: 7x+91 then it can be factored to 7(x+13)


Yun was trying to factor 7x- 14x. He found that the greatest commonfactor of these terms was 7x and made an area model:Width722-14хWhat is the width of Yun's area modelWidth =+=?

It appears there might be some confusion in your notation or expression. To factor 7x - 14x, you can first factor out the common factor, which is 7x. Here's how you do it: 7x - 14x = 7x(1 - 2) Now, the common factor of 7x has been factored out, and you're left with 1 - 2 inside the parentheses. So, the expression 7x - 14x can be simplified to: 7x(1 - 2) Now, it's clear that the width of Yun's area model is 1 - 2, which is equal to -1. So, the width of Yun's area model is -1.

How do you factor 7x plus 49?

Factoring requires you to reduce as much as possible. To factor 7x + 49, you remove the common factor of 7x and 49, which is 7, and multiply (7x + 49)/7 (which is x + 7) by 7, without actually simplifying. 7x + 49 = 7(x + 7) Then, if possible, do the same thing until it cannot be further factored.


How do you factor 14x squared minus 7x to the 3rd power?

I suppose that would be 14x2 - 7x3. Just take out the common factor, 7x2. Divide each term by this factor to find the other factor.
