A Step-By-Step Guide To Writing Polynomials In Standard Form
- A polynomial function ?(?)f(x) of degree ?n is of the form
?(?)=????+??−1??−1+⋯+?1?+?0f(x)=anxn+an−1xn−1+⋯+a1x+a0 - The first term is the one with the biggest power!

When is a polynomial in standard form?
It is a polynomial in standard form when all its terms are ordered in decreasing order of degree; that is when its terms are arranged in decreasing order of degree.
In standard form, the following polynomial looks like this:
X4 + 5×3 – 4×2 + 3x + 6
Since its terms are arranged in decreasing order, the previous polynomial has a standard form. The first term we have is x4, the second term is 5×3, the third term is -4×2, the second term is 3x, and the last term is 6, which is the constant term (degree equal to 0).
In other words, any polynomial whose terms are not arranged in descending order is not in standard form:
6x2 + 5x +2x6 + 4 – 9x5
How To Write A Polynomial in Standard Form
The following steps must be followed to write a polynomial in standard form:
- The like terms of the polynomial should be added together (or subtracted from).
- The highest degree term should be written first.
- The remaining terms should be written in decreasing order of degree.
- It is important to remember that a variable without an exponent is of degree 1.
- Constant terms are of degree 0, so they are always the last.
- The following polynomial will be rewritten in standard form as an example:
Conclusion
A polynomial in standard form is written as ax + bx + cx +… + ex – ex = 0. There are many ways to find the coefficients and constants, but the method shown here is the simplest and works well for all kinds of degrees and orders.
