Factor this completely! 9x^3-x
and show work if you can! :)
thank you!

9x^3 - x
Both terms are multiples of x, so factor it out.
x(9x^2 - 1)
Nine, x^2 and 1 are perfect squares.
The difference of two squares is a special product and can be factored.
x(3x + 1)(3x - 1)
Both terms are multiples of x, so factor it out.
x(9x^2 - 1)
Nine, x^2 and 1 are perfect squares.
The difference of two squares is a special product and can be factored.
x(3x + 1)(3x - 1)
-
9x^3-x = x(9x^2-1) = x(3x+1)(3x-1)
-
9x^3-x = x(9x²-1) = x(3x-1)(3x+1)
