Example Question #8 : How To Find The Degree Of A Polynomial

What is the degree of following polynomial?

\(\displaystyle 400z^{4} + 3z^{7} - 25z + 312\)

Possible Answers:

\(\displaystyle 25\)

\(\displaystyle 4\)

\(\displaystyle 1\)

\(\displaystyle 7\)

\(\displaystyle 400\)

Correct answer:

\(\displaystyle 7\)

Explanation:

The degree of a polynomial with a single variable (in our case, \(\displaystyle z\)), simply find the largest exponent of that variable within the expression. The term \(\displaystyle 3z^{7}\) shows \(\displaystyle z\) being raised to the seventh power, and no other \(\displaystyle z\) in this expression is raised to anything larger than seven. Therefore, the degree of this expression is \(\displaystyle 7\).

Example Question #9 : How To Find The Degree Of A Polynomial

What is the degree of the following polynomial?  \(\displaystyle y=-x^3y^2 + 2x^4\)

Possible Answers:

\(\displaystyle 1\)

\(\displaystyle 5\)

\(\displaystyle 3\)

\(\displaystyle 4\)

\(\displaystyle 2\)

Correct answer:

\(\displaystyle 5\)

Explanation:

The polynomial has more than one variable. The degree of the polynomial is the largest sum of the exponents of ALL variables in a term.

The first term is \(\displaystyle -x^{3}y^{2}\).

The degree of this term is \(\displaystyle 3+2=5\)

The second term is \(\displaystyle 2x^{4}\).

The degree of this term is \(\displaystyle 4\).

The degree of the polynomial is the largest of these two values, or \(\displaystyle 5\).

Example Question #1 : How To Find The Degree Of A Polynomial

What is the degree of the following polynomial?

\(\displaystyle x^{2} + 3x^{7} - 5\)

Possible Answers:

\(\displaystyle 5\)

\(\displaystyle 7\)

\(\displaystyle 2\)

\(\displaystyle 3\)

\(\displaystyle 1\)

Correct answer:

\(\displaystyle 7\)

Explanation:

To find the degree of a polynomial, simply find the highest exponent in the expression.  As seven is the highest exponent above, it is also the degree of the polynomial.

Example Question #4431 : Algebra 1

What is the degree of the following polynomial?  

\(\displaystyle 10x^2 -58x + 12\)

Possible Answers:

\(\displaystyle 2\)

\(\displaystyle 1\)

\(\displaystyle 58\)

\(\displaystyle 12\)

\(\displaystyle 10\)

Correct answer:

\(\displaystyle 2\)

Explanation:

To find the degree of a polynomial, simply find the highest exponent in the expression.  As two is the highest exponent above, it is also the degree of the polynomial.

Example Question #4432 : Algebra 1

What is the degree of the following polynomial?  

\(\displaystyle 3x +4 y + 5z +6\)

Possible Answers:

\(\displaystyle 4\)

\(\displaystyle 6\)

\(\displaystyle 5\)

\(\displaystyle 1\)

\(\displaystyle 3\)

Correct answer:

\(\displaystyle 1\)

Explanation:

To find the degree of a polynomial, simply find the highest exponent in the expression.  As one is the highest exponent above (remember a variable with no visible exponent is being raised to the power one), it is also the degree of the polynomial.

Example Question #4433 : Algebra 1

What is the degree of the following polynomial?

\(\displaystyle 10x^2 + 2y^4 +32z^8\)

Possible Answers:

\(\displaystyle 4\)

\(\displaystyle 8\)

\(\displaystyle 10\)

\(\displaystyle 2\)

\(\displaystyle 32\)

Correct answer:

\(\displaystyle 8\)

Explanation:

To find the degree of a polynomial, simply find the highest exponent in the expression.  As eight is the highest exponent above, it is also the degree of the polynomial.

Example Question #4434 : Algebra 1

What is the degree of the following polynomial?

\(\displaystyle 10x^2y^5z^8 + 2xyz\)

Possible Answers:

\(\displaystyle 5\)

\(\displaystyle 15\)

\(\displaystyle 9\)

\(\displaystyle 2\)

\(\displaystyle 8\)

Correct answer:

\(\displaystyle 8\)

Explanation:

To find the degree of a polynomial, simply find the highest exponent in the expression.  As eight is the highest exponent above, it is also the degree of the polynomial.

Example Question #4435 : Algebra 1

What is the degree of the following polynomial?  

\(\displaystyle 10ab^2 +32a - b - 12\)

Possible Answers:

\(\displaystyle 12\)

\(\displaystyle 1\)

\(\displaystyle 2\)

\(\displaystyle 10\)

\(\displaystyle 32\)

Correct answer:

\(\displaystyle 2\)

Explanation:

To find the degree of a polynomial, simply find the highest exponent in the expression.  As two is the highest exponent above, it is also the degree of the polynomial.

Example Question #4436 : Algebra 1

What is the degree of the following polynomial?  

\(\displaystyle (a^2 + b^2 +c^2)^2\)

Possible Answers:

\(\displaystyle 4\)

\(\displaystyle 2\)

\(\displaystyle 6\)

\(\displaystyle 1\)

\(\displaystyle 8\)

Correct answer:

\(\displaystyle 4\)

Explanation:

To find the degree of a polynomial, simply find the highest exponent in the expression.  At a glance, it appears that two is the highest exponent, however, because the whole polynomial is being squared, the highest exponent (and the exponent of all variables above) is actually four.

Example Question #4437 : Algebra 1

What is the degree of the following polynomial?  

\(\displaystyle 3xyz + 14an + 7u +18y\)

Possible Answers:

\(\displaystyle 14\)

\(\displaystyle 18\)

\(\displaystyle 3\)

\(\displaystyle 1\)

\(\displaystyle 7\)

Correct answer:

\(\displaystyle 1\)

Explanation:

To find the degree of a polynomial, simply find the highest exponent in the expression.  As one is the highest exponent above, it is also the degree of the polynomial.
