Homework Help: math 11 review

Posted by jj86 on Wednesday, February 4, 2009 at 3:29pm.

A couple of extra practice questions I can't remember how to do. Can anyone help?

1. "2*squareroot*5(3*squareroot*7 + 8*squareroot*12)"

I simplified down to 6*squareroot*35 + 2*squareroot*15, but now I am stuck!

2. "The sum of a number and the square of that number is 30. What is the number?"

Is the number 900?

Thanks for any help!
