Answer:
First degree binomial
Step-by-step explanation:
The classification of an expression is based on two factors:
1- the highest degree
2- the number of terms
The given expression is:
5x + 2
We can note that:
1- The highest power is 1, therefore, this is a first degree expression
2- The expression has two terms, therefore, it is a polynomial
Combining the above, we can conclude that the given expression is a first degree binomial
