My question is:

Find the square root -

$(x-1) (x^3 + 4) + (\frac{x}{2} + \frac{2}{x})^2$

The above is a polynomial.I would like to how to find its square root.

    Your'e looking for a polynomial $p(x)$ such that $(p(x))^2=(x-1) (x^3 + 4) + (\frac{x}{2} + \frac{2}{x})^2$, right? (which will not be a plynomial since it will have to include some negative powers of $x$)2012-06-09

    The thing you are claiming is a polynomial is *not* a polynomial.2012-06-09
