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
