Question

Which algebraic expression is a polynomial with a degree of 2?

4x3 − 2x
10x2 − StartRoot x EndRoot
8x3+ StartFraction 5 Over x EndFraction + 3
6x2 − 6x + 5

Answer 1

Option B: $10x^2-\sqrt{x}$ is a polynomial with a degree of 2

Option D: $6x^2-6x+5$ is a polynomial with a degree of 2

Explanation:

The degree of a polynomial means the highest power of the variable in a polynomial.

We need to determine the polynomial with a highest degree of 2.

Option A: $4x^3-2x$

The highest degree of the variable in the polynomial $4x^3-2x$ is 3

Thus, Option A is not the correct answer.

Option B: $10x^2-\sqrt{x}$

The highest degree of the variable in the polynomial $10x^2-\sqrt{x}$ is 2.

Hence, Option B is the correct answer.

Option C: $8x^3+\frac{5}{x}+3$

The highest degree of the variable in the polynomial $8x^3+\frac{5}{x}+3$ is 3.

Hence, Option C is not the correct answer.

Option D: $6x^2-6x+5$

The highest degree of the variable in the polynomial $6x^2-6x+5$ is 2.

Hence, Option D is the correct answer.
