Homework Help: Math

Posted by Lynn on Friday, November 4, 2011 at 2:39am.

Find the value of x.
The area of a rectangle = 105
The length is 2x+1
Width is x
__________________________________

I tried solving it :
Arec = l x w
105 = (2x+1)x
105 = 2x^2 + x
0= 2x^2 + x - 105

This is where I get stuck on...
