1/x equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the equation:
$$\frac{1}{x} = 0$$
Multiply the equation sides by the denominator x
we get:
Move free summands (without x)
from left part to right part, we given:
$$0 = -1$$
This equation has no roots
