Question
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
Options
Monomial
Binomial
Trinomial
Solution
Trinomial
Explanation:
We have, 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.
