Answer:
No
Explanation:
Algebraic Terms:
1. Monomial - an algebraic term
2. Binomial - the sum of 2 algebraic terms
3. Trinomial - an algebraic sum in 3 terms
4. Polynomial - a function in more than 1 algebraic term
The sum of 2 binomials is not always a binomial because each of the two binomials might have different algebraic terms.
If the first binomial has 2 algebraic terms and the second binomial has 2 other algebraic terms and no single term crosses out its coefficients, the sum of both binomials will not be a binomial.
