## What is Polynomial Factoring?

**Polynomial factoring **is the process of finding the factors of a polynomial expression. It involves expressing a polynomial as a product. The goal is to find the roots (**zeros**) of the polynomial and express the polynomial in terms of its factors, which can be useful in solving equations, graphing polynomials, and simplifying expressions.

## Methods of Finding Polynomial Factoring

To find the factoring of polynomials there is no general way to find them, but we have some methods based on formulas, the degree of polynomials, and a number of terms.

**Grouping**

This method involves grouping terms of the polynomial and using common factors to simplify. For example, consider the polynomial** x ^{2} + 6x + 9**. We can group the first two terms,

**(x**, and the last two terms,

^{2}+ 6x)**(6x + 9)**, and factor a common factor of

**3**from each group, giving us

**(3x + 3) (x + 3)**.

**Factoring by grouping**

This method involves grouping terms of the polynomial and then factoring by finding a common factor. For example, consider the polynomial** x ^{3} + x^{2} + x**. We can group the first two terms,

**(x**, and the last two terms,

^{3}+ x^{2})**(x**, and factor a common factor of

^{2}+ x)**x**from each group, giving us

**x (x**.

^{2}+1)**Factoring by inspection**

Looking at the polynomial and finding a pattern that can be factored in. For example, consider the polynomial **x ^{2} + 4x + 4**. We can see that the last term,

**4,**is twice the middle term,

**2x**, so we can factor a common factor of

**2**from the middle term, giving us

**(x + 2) (x + 2)**.

**Factoring by using special formulas**

The method involves using special formulas to factor in specific types of polynomials. For example, consider the polynomial **x ^{2} - z^{2}**. We can factor this using the difference of squares formula, which states that

**a**, giving us

^{2}-b^{2}= (a+b) (a-b)**x**.

^{2}- z^{2}= (x + z) (x - z)## How to calculate quartiles of a data set?

In the below examples, the method of finding factors is explained briefly.

**Example 1**

Find the factors of the polynomial **2x ^{3}+4x^{2}+2x**.

**Solution**

**Step 1:** First we have to take the common from the expression.

`2x(x`

^{2}+2x+1)

**Step 2:** Now we have to make the factor in such a way when we multiply we get **1x^2** and when we add them we get **2x**.

`2x(x`

^{2}+ x + x + 1)

**Step 3: **Now we take the common from **1st **two terms and the last two terms such that

`2x(x(x+1) + 1(x+1))`

**Step 4: **So take the common from the expression we have:

`2x(x+1) (x+1)`

**Example 2: **

Find the factors of the polynomial **x ^{4}-1.**

**Solution:**

**Step 1: **The expression involves two square terms with a minus sign. We have to apply the **a ^{2}-b^{2 }f**ormula:

`a`

^{2}-b^{2}= (a+b) (a-b)

`(x2)`

^{2} – (1)^{2}=(x^{2}-1)(x+1)

**Step 2: **We have again a term to which we can apply the formula

`(x`

^{2}-1) (x^{2}+1) =(x+1) (x-1) (x^{2}+1)

`x`

^{4}-1 =(x+1) (x-1) (x^{2}+1)
