Can someone please help me with my final exam review?

I’m having trouble with a few questions. Answer whichever you can and please help explain so that I can undrestand.

#19. When solving equations algebraically, we have seen two types of equations that can lead to extraneous solutions. What are these two types of equations? How do you check for extraneous solutions in the two cases?

#22. a^4 – 7a^2 + 12 = 0

Solve: (3x-12)(X=5)(2x-3)>0
