$t^{2}-2 t$ નાં શૂન્યો $0$ અને $2$ છે. 

Option A
Option B
Option C
Option D

Solution

A zero of a polynomial $p ( x )$ is a number $c$ such that $p ( c )=0$

Let $p(t)=t^{2}-2 t$

$\therefore \quad p(0)=(0)^{2}-2(0)=0$

And $\quad p(2)=(2)^{2}-2(2)=4-4=0$

Hence, $0$ and $2$ are zeroes of the polynomial $p(t)=t^{2}-2 t$.
