Rhett decides to build a square room for his movie and music collection. If the area of the room is 9x2 − 6x + 1 square feet, what is the length of one side of the room? (3x + 1) feet (9x − 1) feet (3x − 1) feet (9x + 1) feet
9x2-6x+1 9x2-3x-3x+1 3x(3x-1)-1(3x-1) (3x-1)^2 hence answer is (3x-1) right ?
so we just factor this 9x² - 6x + 1 ...and as i was typing...yes you are correct :)
