Question

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

a)4x3 − 2x
b10x2 −
c)8x3+ + 3
d)6x2 − 6x + 5

Answer 1

6x^2 - 6x + 5 <== this is ur polynomial with a degree of 2

the one u have marked is not a polynomial because it has a variable in the square root...a polynomial cannot have that

Answer 2

D) 6x² − 6x + 5 has degree 2.

Explanation:

Given : Polynomial .

To find : Which algebraic expression is a polynomial with a degree of 2.

Solution: We have given polynomial

Degree : The highest power of the polynomial is called degree.

We can see from the given polynomials two polynomial have 2 power

first is
`10x^(2) -√(x)`.

Second is 6x² − 6x + 5.

But the first term have root so, it is not a polynomial.

So 6x² − 6x + 5 has degree 2

Therefore, D) 6x² − 6x + 5 has degree 2.
