Hi june bug,
let x= lenght then width = x-2 Area = 8
x^2 -2x -8 = 0
Factor the quadratic and solve for x
so would the width be -2 and the length be 4? i used the equation x^2-2x-8=0 and solved using the quadratic formula and that's what i got.
you scrap the -2 and use only the 4 and then what is the width ?
2, correct? thank you so much!
