Answer 2

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.

if u understand,,, then like plz..
