Answer:

D. (x² + 3)(x - 3) = 0

Step-by-step explanation:

Simplify (x² + 3)(x - 3) = 0.

(x²)(x) = x³

(x²)(-3) = -3x²

(3)(x) = 3x

(3)(-3) = -9

x³ - 3x² + 3x - 9 = 0

In quadratic equation, the highest exponent is 2.

Therefore, letter D has the highest exponent which is 3. It is considered as a polynomial not a quadratic equation.
