When we rewrite an expression so that it has no grouping symbols and all of the like terms have been combined, we ___ it.

Example: The process of turning (5x - 6) + 10x into 15x - 6.

  "simplify"

Step-by-step explanation:

The notion of simplifying an expression depends on the expression. For the one offered as an example, the simplification steps required are eliminating parentheses and combining like terms.

Other possible simplification steps include combining fractions, reducing fractions, and rationalizing denominators (eliminating surds or complex numbers).

It appears the vocabulary word that is desired in the blank is simplify.

It is simplify. It is what you do when like terms are combined in order to get your answer.

Hope this helps!
