Question

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

Answer 1

9x² - 6x = - 1
x² - 1/3x = - 1/9 + (- 1/3)²
x² - 1/3x = - 1/9 + 1/3
x - 1/3 = 0

= x - 1/3, = 3x - 1

Answer 2

is it 9^2 or 9x2

Answer 3

9x^2

Answer 4

of course @goformit100 it is 9x^2
