Question

Which of these are monomial, binomial, and trinomial

x
3
x+3
3x^2
3x
3x^2+x+3

Answer 1

To classify the given expressions as monomial, binomial, or trinomial:

1. **Monomial**: An expression with one term.
- \( x \) (one term)
- \( 3 \) (one term)
- \( 3x^2 \) (one term)
- \( 3x \) (one term)

2. **Binomial**: An expression with two terms.
- \( x + 3 \) (two terms)

3. **Trinomial**: An expression with three terms.
- \( 3x^2 + x + 3 \) (three terms)

So, the classifications are as follows:

- Monomials: \( x, 3, 3x^2, 3x \)
- Binomial: \( x + 3 \)
- Trinomial: \( 3x^2 + x + 3 \)
