A rectangular vegetable garden will have a width that is 3 feet less than the length, and an area of 54 square feet. If x represents the length, then the length can be found by solving the equation: x (x-3) = 54x (x-3) = 54 What is the length, x, of the garden?

I can't remember the steps to solving this.

Kendrick Buck · Answer 1

x (x-3) = 54

x^2 - 3x - 54 = 0

(x - 9) (x + 6) = 0

x - 9 = 0 so x = 9

x + 6 = 0 so x = - 6

x = 9 (length)

so width = x - 3 = 9 - 3 = 6

answer

length = 9

double check

Area = LxW = 9x6 = 54
