Open in App

Solution

Finding the vaue of given polynomial at $x = 1$
By inserting the value of $x$ as $1$ in the given polynomial, we get ,
$\Rightarrow x^{4} - x^{3} + x^{2} - x + 1$
${\Rightarrow (1)}^{4} - {(1)}^{3} + {(1)}^{2} - (1) + 1$
$\Rightarrow 1 - 1 + 1 - 1 + 1$
$\Rightarrow 1$
Hence, the value of the given polynomial will be $1$ .
