Categorize the expression as a monomial, a binomial, or a trinomial.
7z + 13z^2 - 15
The expression is a trinomial.
Subtract the polynomials.
(-4a^2b + 3ab^2 + ab) - (2a^2b - 3ab^2 - 5ab)
Question 3 options:
A) -6a^4b^2 - 4a^2b^2
B) 2a^2b + 6ab^2 - 4ab
C) -6a^2b - 4ab
D) -6a^2b + 6ab^2 + 6ab
The correct answer is C) -6a^2b - 4ab
What is the degree of the polynomial?
3x^5y^4 - 7x^6 + 3y^3
Question 4 options:
A) 9
B) 20
C) 6
D) 5
The degree of the polynomial is 6. The highest exponent in the polynomial is 6 (in the term -7x^6), which determines the degree. The answer is therefore C) 6.
