5. Which polynomial is written in standard form for the polynomial below?

A. x^5+X^3+X^5+2

B. x^5 - x^3 + 7x^2+2

C. -7x^2 - x^3 + x^5+2

D. 7x^2 + x^3 + x^5+2

Answer 1

2 is C. , 3 is C. , 4 is D.

Explanation:

2

Square roots are not polynomials

3

The highest degree of one term in the polynomial is 4

4

Terms are separated by (+) or (-) signs. If you count them up there are 4

Answer 2

C, D, D, B

Explanation:

2. A polynomial has only integer exponents, no square roots. So C is not a polynomial.

3. The degree of the polynomial is the sum of the exponents of the highest term. p has an exponent of 1 and q has an exponent 4, so 1+4 = 5. D

4. Count the number of terms being added or subtracted. p^3, 4pq^2, q^2, and -3q. So there are 4 terms. D

5. Standard form of a polynomial is written from the highest exponent to the lowest. So the answer is B.
