Question

Verify whether the given statement is true or false:

$\frac{-4}{5}$ is a zero of $4-5y$.

• A. True
• B. False

Answer 1

The correct option is B False

Finding the zero of $4-5y$:

Let $p\left(y\right)=$$4-5y$.

In general, we can say that a zero of a polynomial $p\left(y\right)$ is a number $c$, such that $p\left(c\right)=0$.

To find the zero of $p\left(y\right)$, equate it with $0$, we get,

$\begin{array}{rcl}p\left(y\right)& =& 0\\ 4-5y& =& 0\\ -5y& =& -4\\ 5y& =& 4\\ y& =& \frac{4}{5}\end{array}$

Therefore, $\frac{4}{5}$ is the zero of polynomial $4-5y$.

Hence, the given statement is False.
