Step by step guide to writing polynomials in standard form

  • A polynomial function \(f(x)\) of degree \(n\) is of the form
    \(f(x)=a_{n} x^{n}+a_{n-1} x_{n-1}+⋯+ a_{1} x+a_{0}\)
  • The first term is the one with the biggest power!

Writing Polynomials in Standard Form – Example 1:

Write this polynomial in standard form. \(8+5x^2-3x^3=\)

Solution:

The first term is the one with the biggest power: \(8+5x^2−3x^3=−3x^3+5x^2+8\)

Writing Polynomials in Standard Form – Example 2:

Write this polynomial in standard form. \(5x^2−9x^5+8x^3−11= \)

Solution:

The first term is the one with the biggest power: \(5x^2−9x^5+8x^3−11=
−9x^5+8x^3+5x^2−11 \)

Writing Polynomials in Standard Form – Example 3:

Write this polynomial in standard form. \(-12+3x^2-6x^4=\)

Solution:

The first term is the one with the biggest power: \(-12+3x^2-6x^4=-6x^4+3x^2-12\)
