(8w^4 - 6wz + 6wz^2 ) - ( 2w^4 - 7wz- 2wz^2) :!:

Eliminate the parentheses - be careful to distribute "negative" sign.

Collect same terms (like w^4, wz and wz^2)

and further simplify....

It has been a while since the last post so I will help with the problem just a little more.

Start from were you left off ... Distribute the negative sign on the second group. Once the negative sign is distributed though, remove the parenthesis.

This is what you will have 8w^4-6wz+t6wz^2-2w^4+7wz+2wz^2

All that is left is combining like terms


The Final Answer is 6w^4+wz+8wz^2

Hope that Helps

JeffWest!

Have you figured out how to post with math symbols/ equations?

I really need to figure that out.... =\

I think that there is two ways to post a good math equation.

1. is to use the Sub and Sup tabs at the top right of the reply box. these help you superscript and sub script items. Though I haven't found a way to illustrate division very well.

2. Use Google docs to create your post. it has a great equation editor in it. you can not copy and past the equations,but if you download a text file it preserves the equations and you can then copy and past it from there and it looks really good.

Google is my favorite right now.

LaTeX?

This is what your post would look like had you just put tex tags around your algebra:

This is what you will have \(\displaystyle 8w^4-6wz+t6wz^2-2w^4+7wz+2wz^2\)

All that is left is combining like terms


The Final Answer is \(\displaystyle 6w^4+wz+8wz^2\)

For division just use the \frac{numerator}{denominator} element:

\(\displaystyle \frac{numerator}{denominator}\)

 

[JeffWest]

\(\displaystyle 6x^2\)

\(\displaystyle \frac{4}{3}\)

division just use the \frac{numerator}{denominator} elem

thanks daon

\frac{4}{3}

= (

\(\displaystyle \frac{4}{3}\)

= )
