Question 56 (d)
Simplify the following by combining the like terms and then write whether the expression is a monomial, a binomial or a trinomial.
2a + 2b + 2c - 2a - 2b - 2c - 2b + 2c + 2a
2a + 2b + 2c - 2a - 2b - 2c - 2b - 2c + 2a
By combining the like terms.
= 2a - 2a + 2a + 2b - 2b - 2b + 2c - 2c + 2c
= 2a - 2b + 2c
The expression contains three terms. So, it is trinomial.
