Answer:

(2x+9) ^3

Step-by-step explanation:

(((8 • (x3)) + 729) + (22•33x2)) + 486x

((23x3 + 729) + (22•33x2)) + 486x

Factoring: 8x3+108x2+486x+729

8x3+108x2+486x+729 is a perfect cube which means it is the cube of another polynomial

In our case, the cubic root of 8x3+108x2+486x+729 is 2x+9

Factorization is (2x+9)3
