to solve Q(x) + R(x)/ 2x+3

so far:
6x^4+17x^3+16x^2+14x+12

how do I get the above substitution?

Cheney's 1% Doctrine posits that if there is only a 1% chance of our enemies using or obtaining WMD's we must respond as if the threat was 100%. When you take action based on a 1% certainty, what are the probabilitys that your assumption is correct vs incorrect. Is there a 99% probability that your assumption is incorrect, or something less?

Yes, and please specify what kind of power source I should use. Is a 9-volt battery enough? How about three button cells?

I am supposed to make an open circuit and let the current pass through the body in order to close it. I do not know which is appropriate: 9-volt battery powering a buzzer OR three button cells powering LEDs.

I am afraid of giving myself an electric shock though; I do wish to be careful at least.
