4. which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − 8x3 3 6x2 − 6x 5

CaHeK987 [17]

ANSWER

The algebraic expression that is a polynomial with a degree of 2 is
$6 {x}^{2} - 6x + 5$

EXPLANATION

The degree of a term of a polynomial is the total sum of the exponents of the variables in each term.

The highest degree of the polynomial is considered the degree of the polynomial.

For first option,
$4 {x}^{3} - 2x + 10$
the highest degree is 3.

The second option is,
${x}^{2} - 8 {x}^{3} + 3$
This polynomial also has a degree of 3.

The third option is,
$6 {x}^{2} - 6x + 5$
This last option has a degree of 2.

Therefore the correct answer is option C.
