In mathematics, polynomial identity testing (PIT) is the problem of efficiently determining whether two multivariate polynomials are identical. More formally, a PIT algorithm is given an arithmetic circuit that computes a polynomial p in a field, and decides whether p is the zero polynomial. Determining the … See more The question "Does $${\displaystyle (x+y)(x-y)}$$ equal $${\displaystyle x^{2}-y^{2}\,?}$$" is a question about whether two polynomials are identical.
