The binomial theorem tells us that the expansion of EQN:(x+y)^n is given by:

EQN:c_0x^n+c_1x^{n-1}y+c_2x^{n-2}y^2+...+c_ny^n |>> $c_0x^n+c_1x^{n-1}y+c_2x^{n-2}y^2+...+c_ny^n$ <<|

where the EQN:c_i are the binomial coefficients.
Writing the expansion using the binomial coefficients we get:


The coefficients are exactly the numbers in the appropriate row of Pascal's Triangle.
