Please help? I have been doing this one problem for hours

Claudia has a rectangular flowerbed. She decided that the original width w, in feet, was too small, so she increased the width by 3 feet. She also changed the length to be 1 foot less than twice the original width. The new area of her flowerbed is 72 square feet. How many feet wide was the original flowerbed?

A = Length x Width

72 = (w+3) (2w-1)

0 = 2w^2+5w-75
