The polynomial remainder theorem states that the remainder of the division of a polynomial
by
is equal to
.
Therefore

Xy=130
y=3+x
x(3+x)=130
x²+3x-130=0
(x+13)(x-10)=0
x= -13 or 10
since the question says X and Y are positive we just dismiss-13
x=10
and y=13
Hi i don’t really know the answer but i just wanted to say good luck on ur exams and you will do great!!
