Question

Rhett decides to build a square room for his movie and music collection. If the area of the room is 16x2 − 24x + 9 square feet, what is the length of one side of the room?
(4x + 3) feet
(16x + 3) feet
(16x − 3) feet
(4x − 3) feet

Answer 1

Answer:

16x^2 - (12+12)x + 9

16x^2 -12x -12x +9

4x(4x-3)-3(4x-3)

(4x-3)(4x-3)

hence length of one side is 4x-3
