Question

The length of a rectangular room is two feet less than three times its width. The area of the
rectangle is 176 square feet.

a) Write an algebraic equation to model this problem.
b) Solve the equation to find the dimensions of the rectangle.

Another tutor helped me and I was able to find the
y(width) solution set (y=8,-22/3) but I couldn't find the length
negative dimensions are extraneous solutions
... they have no "real world" meaning

divide the area by the width to find the length
