Question

Find the number of terms and degrees of each polynomial: -b3+ b2 + 20b - 4.

(A) 1
(B) 2
(C) 3
(D) 4

Answer 1

The polynomial has four terms with respective degrees of 3, 2, 1, and 0. Option (D) is correct.

Step-by-step explanation:

The given expression is a polynomial in the variable 'b' with four terms: -b3 + b2 + 20b - 4. The number of terms in this polynomial is four, which corresponds to option (D). The degree of each term respectively is 3, 2, 1, and 0. The highest degree of these terms is 3, which also indicates the degree of the polynomial.
