$3 x+1$ નું શૂન્ય $-\frac{1}{3}$ 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 $p(x)=3 x+1$
$\therefore \quad p\left(-\frac{1}{3}\right)=3\left(-\frac{1}{3}\right)+1=-1+1=0$
Hence, $-\frac{1}{3}$ is zero of $p ( x )=3 x +1$
