WebThis means x − a is a factor of x n − a n. x n − a n = ( x − a) ( x n − 1 + a x n − 2 + ⋯ + a n − 1). Replace x and a with a and b. Just multiply out the right hand side, you'll see that all terms except for the left hand side cancel. This seems to me to be the best explanation of that factorization.
WebWhere: X – the number of items that belong to set A Y – the number of items that belong to set B Z – the number of items that belong to set A and B both. From the above Venn diagram, it is quite clear that. n(A) = x + z n(B) = y + z n(A ∩ B) = z n(A ∪ B) = x +y+ z.
