An online expansion calculator of algebraic expressions is presented. The binomial theorem [1,2] states that a polynomial of the form \( (x + y)^n \) may be expaneded as a sum of terms in volving powers of \( x \) and \( y \) as follows: \[ (x + y)^n = \sum_{k=0}^{n} {n\choose k} (x)^{n-k} (y)^k \] where \( {n\choose k} \) is called the binomial coefficient and is given by \[ {n\choose k} = \dfrac{n!}{k!(n-k)!} \] Example Expand the expression \[ (x - 2y)^4 \] Solution Use the theorem above to write \( (x - 2y)^4 = (x + (-2y))^4 = \sum_{k=0}^{4} {4\choose k} (x)^{4-k} (-2y)^k \\ \quad = {4\cho
