If the degree of (x^4+ax^2+7) is (4), what is the correct statement about (a)?

Answer and explanation

Correct answer: (a) can be any real number

The degree of a polynomial is determined by the highest power whose coefficient is not zero. In the expression x^4+ax^2+7, the coefficient of x^4 is fixed as 1. Since 1 is never zero, the x^4 term is always present, regardless of the value chosen for a. The middle term may disappear, but that cannot lower the degree below 4.

If a=0, the expression becomes x^4+7 and still has degree 4. If a is non-zero, the x^2 term is present, but x^4 remains the highest power. Thus every real value of a gives degree 4. Option A is correct. The value a=4 is not required, and a≠0 is unnecessary because zero also works.
