Answer:
(x+5) and (x-10).
It is in the form of {x+a)(x+b)=x²+(a+b)x+ab.
x=x. a=5. b=-10.
(x+5)(x-10)=x²+(5+(-10))x+(5)(-10).
=x²+(5-10)x-50. (Because +×-=-).
=x²+(-5)x-50.
=x²-5x-50.
(or).
x²-5x-50=0.
x²-10x+5x-50=0.
x(x-10)+5(x-10)=0.
(x+5)(x-10)=0.
(or).
x+5=0. x-10=0.
x=-5. x=10.
I think this is your answer.
