Answer:
The expression consists of two factors, and each factor contains three terms.
Step-by-step explanation:
Factors are numbers that multiply. The two brackets are written stuck to each other without any symbol between them, which means they are multiplying.
(a+b+c) is the first factor.
(d+e+f) is the second factor
Terms are numbers that separated by addition or subtraction.
Inside the first bracket, the terms are "a", "b", and "c".
Inside the second bracket, the terms are "d"", "e", and "f".
