Verify whether the following are True or False:
$\frac{-4}{5}$ is a zero of $4-5 y$
Verify whether the following are True or False:
$\frac{-4}{5}$ is a zero of $4-5 y$
A zero of a polynomial $p ( x )$ is a number $c$ such that $p ( c )=0$
Let $p(y)=4-5 y$
$\therefore \quad p\left(-\frac{4}{5}\right)=4-5\left(\frac{-4}{5}\right)=4+4=8 \neq 0.$
Hence, $-\frac{4}{5}$ is not a zero of $4-5 y.$
