Answer 2

Sum of the roots of $x^{5}-5x^{3}+x+1=0$ is option (1)

Definition:

If we have the general polynomial like this

      $f(x)=ax^{n}+bx^{n-1}+cx^{n-2} +..+z$

Then the sum of the roots of the equation is given by $-\frac{b}{a}$

Step-by-step explanation:

The given expression can also be written as $x^{5}+0x^{4} -5x^{3}+0x^{2} +x+1=0$

From the above expression ,it can be seen that $a=1,b=0$

So the sum of the roots:

$=-\frac{b}{a} \\=-\frac{0}{1} \\=0$

Therefore,the sum of the roots of the equation is 0 that is option (1)
