Answer:
x(3x+1)(3x-1)
Step-by-step explanation:
factor x out = 9x^2 -1. notice that 1 * x = 1, thats why theres a 1 now.
(This is called the difference of two squares. Since 1 is a square(1^2 = 1).)
Next factor the first part = 3 * 3 = 9 x * x = x^2.
So far we have x(3x - )(3x + ). The blank spaces show what we don't know.
The second part is easy. 1 * 1 = 1, so we fill in the spaces to get x(3x+1)(3x-1)
happy new years eve!
