(x^2-16)/(x+4)=0 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the equation:
$$\frac{x^{2} - 16}{x + 4} = 0$$
transform:
$$\frac{\left(x - 4\right) \left(x + 4\right)}{x + 4} = 0$$
$$x - 4 = 0$$
Move free summands (without x)
from left part to right part, we given:
$$x = 4$$
We get the answer: x = 4
