Answer:
5y^2 + 10y + 5x^2
Step-by-step explanation:
there's only two like terms that can be combined.
Answer:
1. Binomial 2. Trinomial 3. Trinomial 4. Polynomial 5. Polynomial 6. Polynomial 7. Trinomial 8. Binomial 9. Polynomial 10. Monomial
Step-by-step explanation:
For future references, you can use this to find out what the expression (number of its terms) is...
Monomial > One term = 2x^5
Binomial > Two terms = x^2 + 5
Trinomial > Three terms = 3x - 8 + 4x^5
Polynomial > Four terms (or more) = -7a^2 + 9b - 4b^3 + 6
