First you need to distribute the 9.
So 9 times 3 and 9 times 2
The Algebraic should look like now: (27^3x-18)
So the final answer is: [tex]27x^{3} - 18[/tex]
You cannot simplify it anymore because there are no like terms left.
first you have multiply 9 time all inside the parethesys.
9 time 3= 27
9 time -2=18
the 9 doesn't affect the exponent 3
27x^3-18
