Answer:
15p
Step-by-step explanation:
<u>Let's interpret the question bit by bit</u>
<em>Salvador wrote 15 letters to friends each month</em>
=> 15 letters = 1 month
<em />
<em>For p months in a row</em>
let the total number of letters for p months be x
=> x letters = p months
<em>Bringing the two statements together gives;</em>
15 letters = 1 month
x letters = p months
<em>Now, let's solve for </em><em>x </em><em>by cross-multiplying the above</em>
x letters * 1 month = 15 letters * p months
x = ![\frac{15 letters * p months}{1 month}](https://tex.z-dn.net/?f=%5Cfrac%7B15%20letters%20%2A%20p%20months%7D%7B1%20month%7D)
x = 15p letters
Therefore, Salvador wrote a total of 15p letters for the p months.
The GCF of a polynomial is the greatest factor which is common to all the terms of the polynomial.
Thus, an example of a polynomial with a GCF of 2y is
![6y^3-12y^2+4y](https://tex.z-dn.net/?f=6y%5E3-12y%5E2%2B4y)
The above polynomial can also be rewritten as
![2y(3y^2-6y+2)](https://tex.z-dn.net/?f=2y%283y%5E2-6y%2B2%29)
This form of the polynomial is obtained by factoring out the GCF of the polynomial.
