# Polynomial Step-by-step Functionality

We’re excited to introduce some brand new features to our step-by-step functionality! Wolfram|Alpha can now guide you through factoring polynomials and completing the square, in addition to being updated to include FOIL and the binomial expansion theorem. Let’s take a look.

How about factor x^4 + x^2 + 1:

Looking at completing the square, three methods are offered! Let’s try complete the square x^2 + 2x + 3:

Perhaps we’d like the center of a circle:

Lastly, let’s take a look at our updated expansion steps.

How about expand (x^2 + x + 1)(x^2 – x + 1)(x – 3):

Stay tuned for more step-by-step functionality releases very soon!

*Wolfram|Alpha Pro users have unlimited access to step-by-step features.*

Wow, where was this when I needed it in school? It’s one thing for a math workbook to simply provide an answer, but that doesn’t always help when you don’t know how to get there. This is a great tool – the step-by-step assistance is fantastic, and this will hopefully be able to get students past their trouble points to arrive at the correct answer.
