question :(adsbygoogle = window.adsbygoogle || []).push({});

if p is a common factor of the equations f(x)=0, and g(x)=0, prove that p is also a root of the equation af(x) + bg(x) where a and b are constants.

i want to know the working.

i dont think the working will be like this :

af(p) + bg(p) = a(0) + b(0) = 0

so, i need the correct working here. thanks.
