Question 57965
A rectangular painting with a width of x centimeters has an area of x^2+50x square centimeters. Find a binomial that represents the length. 
:
We know area = L*W:  x^2 + 50x = the area. and tells us the width = x. Find 
length by dividing (x^2 + 50x) by the width which is given as x
:

{{{(x^2 -50x)/x}}} = (x + 50) is the length
