Answer 1

D. -2

Explanation:

Let order the polynomial in standard form:

`4\cdot x^(7) + x^(6) - 2\cdot x^(2) - 4\cdot x + 3`

The value of the coefficient in the second-degree term is -2. Hence, the right answer is D.

Answer 2

(D)-2

Explanation:

The degree of a term in a polynomial is the power of the variable in that term.

In the polynomial:

`x^6 + 3 - 2x^2 + 4x^7 - 4x`

The coefficient of the term of degree 2 is the number beside x raised to the power of 2.

This coefficient is -2.

The correct option is D.
