<PRE><B>Question 1102687</B>
The area of a rectangular wall in a classroom is 308 feet.  Its length is 5 feet shorter than three times its width.  Find the length and width of the wall of the classroom.

So the equation is w(3w-5)=308, right? and that turns into {{{3w^2-5w=308}}}. And then you complete the square? But I can seem to be able to find any real solutions. Can you help?
-------------
3w^2 - 5w - 308 = 0
