What is the polynomial standard form?

Each equation type has its standard form. Radical equation? Check. Rational equation? Check. This means there is also a standard form of polynomial or exponential equations.

The standard form of the polynomial equation is obtained by ordering elements in the descending order of degrees. Its general form is 

polynomial standard form

Let’s see some examples of these equations.


Order the following equation in standard form. 

7x - 3 + 5x2


Step 1: See the order of the polynomial.

The highest degree tells the order of the polynomial equation. In this example, the order of the polynomial is 2.

Step 2: Write the element with degree 2 in the first place.

5x2 is the required element.

5x2 + (second value) + (third value)

Step 3: Place the degree 1 value.

7x has the power one.

5x2 + 7x + (third value)

Step 4: Input the last value with the variable degree 0.

5x2 + 7x - 3.

This is the standard form of the given equation.

Example 2:

Arrange the following equations in the standard form

  1. x5 - 4x + 2x10
  2. 1 + 8x3 + x + x2
  3. 7 + 7x + 7x2 + 6x3 + 6x4 + 6x5


  1. 2x10 + x5 - 4x
  2. 8x3 + x2 + x + 1
  3. 6x5 + 6x4 + 6x3 + 7x2 + 7x + 7

Factorization of polynomial equation

Factorization, as you might know, is the process of breaking down a value into smaller values which on multiplication give the original equation or function. Quadratic equations can be broken down by quadratic formula and completing squares.

But a general method is to arrange the equation into standard form and simplify it. It is best explainable by an example. 

Consider that you have the equation  9x + 6x2y + 3xy. Let’s find its factors.

Firstly, arrange this equation into standard form.

= 6x2y + 3xy + 9x

See what you can extract from this equation. This value will be the GCF of all three entries of the equation. 

= 3x (2xy + y + 3)

So, 3x is the GCF of the equation 6x2y + 3xy + 9x. Now, this equation is at its simplest. It cannot be solved further.

Hence, the factors of this equation are 3x and 2xy + y + 3.

Polynomial graph plot

When a polynomial equation is plotted on a graph, the x-intercepts give the factors of the equation. For example

Polynomial graph plot

This is the graph of the polynomial equation x2 + 2x + 1. You can determine its factors by looking at the x-intercept.

The factors of this equations are x = -1 and x = -1.

Factorization over a finite field

The calculator above finds the factors of the equation in the Galois field 2. GF(2) is the smallest finite field that exists with the elements 0 and 1. 

Its resemblance to the binary system and boolean algebra makes it really useful in computer science and related fields.
