Sam decides to build a square garden. If the area of the garden is 9x2 - 24x + 16 square feet, what is the length of one side of the garden?

(3x + 4) feet
(3x - 4) feet
(4x - 3) feet
(4x + 3) feet

Respuesta :

area of square = (side)^2

so 9x2 - 24x + 16

= (3x)^2 - 2*(4)*(3x) + 4^2

= (3x - 4)^2

so side = 3x - 4
