Question
Simplify the following by combining the like terms and then write whether the expression is a monomial, a binomial or a trinomial.
50x3 – 21x + 107 + 41x3 – x + 1 – 93 + 71x – 31x3
Options
Monomial
Binomial
Trinomial
Solution
Trinomial
Explanation:
We have, 50x3 – 21x + 107 + 41x3 – x + 1 – 93 + 71x – 31x3
By combining the like terms,
= 50x3 + 41x3 – 31x3 – 21x – x + 71x + 107 + 1 – 93
= 60x3 + 49x + 15
The expression contains three terms. So, it is trinomial.
Notes
We can add and subtract only like terms.
