## How many factors does a polynomial of degree 3 have?

3 factors

Note there are 3 factors for a degree 3 polynomial. When we multiply those 3 terms in brackets, we’ll end up with the polynomial p(x).

**How do you factor polynomials with more than 3 terms?**

Just follow these steps:

- Break up the polynomial into sets of two. You can go with (x3 + x2) + (–x – 1).
- Find the GCF of each set and factor it out. The square x2 is the GCF of the first set, and –1 is the GCF of the second set.
- Factor again as many times as you can. The two terms you’ve created have a GCF of (x + 1).

### How do you factor polynomials without common factors?

If you have four terms with no GCF, then try factoring by grouping.

- Step 1: Group the first two terms together and then the last two terms together.
- Step 2: Factor out a GCF from each separate binomial.
- Step 3: Factor out the common binomial.

**Why do we factor polynomials?**

The purpose of factoring such functions is to then be able to solve equations of polynomials. For example, the solution to x^2 + 5x + 4 = 0 are the roots of x^2 + 5x + 4, namely, -1 and -4. Being able to find the roots of such polynomials is basic to solving problems in science classes in the following 2 to 3 years.

## How to factor polynomials with 4 terms?

Set up the synthetic division.

**How to make a polynomial?**

The Standard Form for writing a polynomial is to put the terms with the highest degree first. Example: Put this in Standard Form: 3 x2 − 7 + 4 x3 + x6 The highest degree is 6, so that goes first, then 3, 2 and then the constant last:

### How do you calculate polynomials?

Calculating the volume of polynomials involves the standard equation for solving volumes, and basic algebraic arithmetic involving the first outer inner last (FOIL) method. Write down the basic volume formula, which is volume=length_width_height. Plug the polynomials into the volume formula. Example: (3x+2)(x+3)(3x^2-2)

**What is a third degree polynomial?**

Third degree polynomials are also known as cubic polynomials. Cubics have these characteristics: One to three roots. Two or zero extrema. One inflection point. Point symmetry about the inflection point. Range is the set of real numbers. Three fundamental shapes.
