Take the 9 out,

Answer 2

could you solve this step by step?

Answer 3

9x^3 -54x^2+72x
9(x^3 -6x^2+8x)

Hint:
factors of 8
1 & 8
2 & 4
the constants will be both negative because the add up to negative number and multiply to a positive number.
the constants have to
add up -6 and multiply to 8

-2 + (-4)= -2-4=-6 and
(-2) * (-4)= 8

so
9 (x-2) (x-4)
