**Reiny**, Wednesday, March 4, 2009 at 11:58amX^2 +50x factors and

= x(x + 50)

clearly, x must be a positive number, so clearly x+50 is larger than x

Usually, in talking about length and width, the length is the larger of the two dimensions, isn't it ?

So, what do you think?

**Reiny**, Wednesday, March 4, 2009 at 12:41pmArea = width x length

X^2 +50x = x(x+50)

so x must be the width

x+50 must be the length
