    The answer is quadratic.

    A quadratic equation takes this form:

    ax^2 + bx + c

    The "a,""b,"and "c" represent numerical coefficients.

    This is how your equation looks:

    3x + x^2 + 4

    Now it is standard that we organize the polynomial in descending order so it will look like this:

    x^ 2 + 3x + 4

    (commutative property of addition says that the arrangement will not affect the result)

    It matches the quadratic polynomial form.

    * You might be thinking, x to the second power has no number next to it though, well actually it does. The numerical coefficient of x to the power of two in this case is actually 1. It's just that in math, it is not necessary to put the one anymore. It is already assumed.
