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.

$\therefore \text{when}x=5$, the value of the expression $x-5$ is 0.
Hence, the root of the given equation is 5.
