Area=432

width is 6 feet less than length. what's the length.
I haven't done this since the beginning of the year so I could really use the help remembering how.

length ---- x
width ------ x-6

x(x-6) = 432
x^2 - 6x - 432 = 0

solve as a quadratic. hint: it factors, but the quadratic formula will
also give you the answer.
Personally, I would have completed the square.
