Answer 2

Answer:

1)5

2)like

3)monomial

4)coefficients

5) -p

Step-by-step explanation:

• Degree of a polynomial is the highest power of its variables. For example:- The degree of the polynomial x³ + 2x is 3.

• Like terms are the terms which have same variables and the same power of variables but have different coefficients. For example :- 9x²y and -7x²y.

• Monomials have one term,binomials have two terms and trinomial have three terms. 2x is a monomial,6x²+4 is a binomial and 4x²+y+z is trinomial.

Addition of like terms :-

• Addition of like terms is very easy.Just add their coefficients and write the variable. For example :-

8pq + 9pq -6pq = (8+9-6)pq = 11pq
