Question

Find the roots of the equation $x-5=0$.

• A. 5
• B. -5
• C. 0
• D. Not defined.

Answer 1

The correct option is A

5

$x-5=0$ signifies that $(x-5)$ is a polynomial whose value is zero for a certain value of $x$ and this $x$ will be the root of the given equation.
$\therefore \text{At x=5, the value of expression x-5 is 0.}$
Hence, the root of the given equation is $5.$
