Answer:
Yes, x-5 is a factor of this quadratic equation.
THIS IS EXPLAINED AS BELOW :-
P(E) =x^2-3x-10=0
Now, by the algebraic expressions method,,,,
x^2-5x+2x-10 = 0
=x(x-5) +2(x-5) = 0
=(x-5)(x+2) = 0
either,
(x-5) = 0 or (x+2) =0
So, according to your question (x-5) is a factor of this quadratic equation.
