Adding or Subtracting Radicals

Relax you can do this! I have to admit after chanting that to myself several times it helped. Oh and also telling my junior high student at the kitchen table helped too. Some of this math they bring home is crazy looking or is it just me here?

What the heck is a Radical?

A radical is a symbol √ that is used to indicate the square root or nth root of a number.

Clear as mud right?

Most times a simple jogging of the memories of my math torture (ahem) I mean math classes I usually can jump into to explaining things. However this assignment had both of us puzzled. I am determined to explain it though because if my kid is stuck then the kids at school will be too.

First of all thank you to the mighty internet gods for Google. Anywhere, anytime and any subject my second brain has come in so handy. Now I am not sure about you but I am definitely an application learner. I always need my scratch paper to mindfully plan out the steps to solving math equations. So find the method that helps you the best.

When is a radical simplified?

We say that a SQUARE ROOT RADICAL is simplified, or in its simplest form, when the radicand has no square factors.

How do I get started?

1. Simplify each radical expression.

2. Combine like radicals if there are any.

*Remember you can only add or subtract similar radicals.

3. Once everything is simplified you are done. Cue smile!

Where would you ever use radicals or radical expressions?

Radical expressions are mathematical expressions that contain a square root. They are commonly found in trigonometry and geometry. Radical expressions are found in carpentry, masonry and electrical engineering.

Here are some awesome video finds that clearly explain how to solve this homework:
