(x-2)\cdot(x-(1+\sqrt[]{5}))\cdot(x+\sqrt[]{3})

If one choose the first factor (which is the conjugated binomial of x-2) and add it to our polinomial we would have:


\begin{gathered} (x+2)\cdot(x-2)\cdot(x-(1+\sqrt[]{5}))\cdot(x+\sqrt[]{3}) \\ (x-2)^2\cdot(x-(1+\sqrt[]{5}))\cdot(x+\sqrt[]{3}) \end{gathered}

This means, for the first factor, 2 is a root of multiplicity 2.

The sentence specify that the polinomial has multiplicity of 1 for each root, therefore, we cannot use either the conjugated binomial or the square binomial of the roots.

Thus, the only factor which is not changing the multiplicity is:


x+(1-\sqrt[]{3})
