An enzyme is a protein that is used as a catalyst in a reaction within an organism. This is used in such a way that it lowers the energy requirement for a specific reaction to occur and this could either ...

3x^2-8x-3 factorises into (3x+1)(x-3)2x^2-6x fatorises into 2x(x-3)Common factor between the numerator and denominator is (x-3)therefore the final answer is (3x+1)/2x

We’d use filtration. The mixture is poured over filterpaper in a funnel. The solid(residue) is left behind and the filtrate is pure liquid with no solid.
