b- -8ab +7c + 8ab
c- 5ab² –6a + 2c
d- ab + bc + ca

Answer 1

Answer:

a. Yes

b. No

c. No

d. No

Step-by-step explanation:

Here, the first thing we need to do is to solve the expressions and then regard as monomial, binomial, trinomial, multinomial etc. Let's solve the equations :-

a. 3ab²+ 5b – ab² = 3ab ² – ab² + 5b = 2ab² + 5b

Here we got the solution as two terms. Therefore, it is a binomial.

b. –8ab + 7c + 8ab = –8ab + 8ab + 7c =

We will cancel–8ab and 8ab as they have opposite signs.

= 0 + 7c = 7c

Here, we got the answer as one term only, so it is not a binomial.

c. 5ab² – 6a + 2c = Here, it will remain the same. And, it is not with two terms too, so it is not a binomial.

d. ab + bc + ca = 2a + 2b + 2c

Here, we got the answer as three terms, so it is not a binomial.

Hope it is all clear to you. Please mark as brainiest and follow me.
