quadratic word problem

Question

your uncles garden is the shape of a rectangle and has a length of 8 feet less than twice the width. the area of the garden is 640 feet squared. write an equation using x as your variable to model this situation.

Answer 1

w(2w - 8) = 640

2w² - 8w = 640

w² - 4w = 320

w² - 4w - 320 = 0

Answer 2

w represents the width

2w - 8 represents the length

w(2w - 8) = 640
