Hi thank you for the demonstration. The definition of a parallelogram is " A parallelogram is a quadrilateral with Both pairs of Opposite Sides Parallel. This implies the opposite sides are equal as one of the properties of a parallelogram.

Yes that's right, but we try to make the videos as clear as possible for everyone to understand :)

Given that f(x)=x^2×n-(p+1)x^2+p, where n and p are positive integers. Show that x-1 is a factor of f(x), for all values of p. when p=4, find the value if n for which x-2 is a factor of f(x) and hence factorize f(x) completely.
