    You've treated the +20 as +20x, I would put an extra term "+0x" in the middle to prevent mix ups (See my solution below)

    I'm kidding, but yeah you need a coefficient of each power of x before trying to divide using long division. (e.g. to divide 3x^4+2x^2+18 by whatever root you find you would need to divide by 3x^4+0x^3+2x^2+0x+18 instead, always remember this step! it'll make a huge difference.
