    a 4 term polynomial is a cubic, correct? if you put it in standard form, you put it in this form: \[y=ax^3+bx^2+cx+d\]

    so if you have: \[y=(x+3)^3\] how to get it into standard form (general form) is to expand it. Make sure that all your indices go from highest to lowest

    do you know how to expand cubics, or polynomials in general?

    \[(x+2)^2\]\[(x+2)(x+2)\]\[x(x+2)+2(x+2)\]\[x^2+2x+2x+4\]\[x^2+4x+4\]

    of course, there are shortcuts, but seeing as you should learn the basics first, this ^ is how you should so it
