Im stuck on this 2 problems.. help plz! 1.) P = {x E N/x^2 -9=0} 2.) F = {x E Q / (3x-4)(x-√2)=0} Thank you! I'll appreciate it

Afterwards check if the solutions belong to the given domain. 3. An example: A product equals zero if one of the factors equals zero: As you easily can see only y = 1 is a valid solution. Thus
That's my problem...I don't know how to use this theory on the problems i was given. I'm not that good at mad :-s
