Column A is greater
Column B is greater
The columns are equal
The relationship cannot be determined

Expanding Column A's binomial yields  .
Expanding Column B's binomial yields  .
Dropping like terms in both expressions, we find that Column A contains 9x, and Column B, 12x.
Since x < 0, Column A is always greater than Column B.
You can double-check your choice by picking numbers like –1, –2, and
.
