Continue this process decrementing the power of x and incrementing the power of y until you place the term y n next to the final number 1x 5 5 x 4 y 10x 3 y 2 10x 2 y 3 5xy 4 1y 5 Exercises Expand (2x y) 4 (x y) 6(xyz)^3 (x y z)(x y z)(x y z) We multiply using the FOIL Method x * x = x^2 x * y = xy x * z = xz y * x = xy y * y = y^2 (xy)^3 (yz)3 (zx)^3 = 3(xy)(yz)(zx) That is it no constraints etc It mentions "This can be done by expanding out the brackets, but there is a more elegant solution" Homework Equations The Attempt at a Solution First of all this only seems to hold in special cases as I have substituted random values for x,y and z and they do not agree
