Simplifying Algebraic Expressions
Y(4) = 2 1 Rewriting the LHS in di erential form and factoring the RHS we getWe can try to factor x 2 −2xy−y 2 but we must do some rearranging first Change signs y 2 2xy−x 2 = − 1 k 2 Replace − 1 k 2 by c y 2 2xy−x 2 = c 1 the expression (x – y)^ 2xy y^ is an example of?
By taking LHS, (x – y) 2 = (x – y) (x – y) (x – y) 2 = x 2 – xy – xy y 2 (x – y) 2 = x 2 – 2xy y 2 LHS = RHS Hence, proved x 2 – y 2 = (x y) (x – y) By taking RHS and multiplying each term (x y) (x – y) = x 2 – xy xy – y 2 (x y) (x – y) = x 2 – y 2 Or x 2 – y 2 = (x y) (x – y) LHS = RHS Hence provedLHS = x 2 2xy y 2 LHS = RHS (x – y) 2 = x 2 y 2 – 2xy; $$ i^2 = j^2 = k^2 = 1 \\ ij = jk = ki = 1 $$ which sort of look like quaternions, but not quite In this case the factorisation becomes, $$ x^2 y^2 z^2 2xy 2yz 2zx = (ix jy kz)^2 $$ I didn't know if there was some algebra which obeyed these properties
