Why do areas on the west coast of mexico central america and south america experience lot of seismic activity

I think this is the answer Mexico’s location makes the country prone to strong earthquakes because it is in a so-called subduction zone.

Subduction zones are the parts of the earth where one slab of the crust is slowly sliding under another. In Mexico’s case, an oceanic plate — the Cocos — is gradually sinking beneath a continental plate — the North American.

Over time, stress builds because of friction between the slabs, and at some point, the strain becomes so great that all the pent-up energy is released in the form of an earthquake.

The subduction zone responsible for the two recent quakes runs along the western coast of Central America, from Central Mexico to Panama, said Gavin Hayes, a research geophysicist with the United States Geological Survey. Other subduction zones are found across the globe — and experts say they are responsible for the world’s most powerful earthquakes.

But if is not please tell me

2. x2 + 8x + 12 = 0 to prove: x = -6 or x = -2

Where's the we need to see the it could be any country!
