Question
Explain how to use a polynomial identity to factor 
.
Hint:
, where a and b can be real values, variables or multiples of both.
We are asked to explain how to use a polynomial identity to factor
The correct answer is: polynomial
Step 1 of 2:
Factoring a polynomial is the process of decomposing a polynomial into a product of two or more polynomials. This can be done with the help of identities, which would speed up the process and make it simple.
The given polynomial is 
. It can be written as: 
here 
.
Step 2 of 2:
Substitute the values of in the identity;
Thus, the factor is: 
Thus, the factor is:
We use identities to speed up the process of multiplication and simplification. There are some basic polynomial identities that you need to by heart.

Explain why the middle term is 10x.
In the Binomial Expansion's middle term, in the expansion of (a + b)n, there are (n + 1) terms. Therefore, we can write the middle term or terms of (a + b)n based on the value of n. It follows that there will only be one middle term if n is even and two middle terms if n is odd.
The binomial expansions of (x + y)n are used to find specific terms, such as the term independent of x or y.
