SOLUTION 1 Begin with x3 y3 = 4 Differentiate both sides of the equation, getting D ( x3 y3 ) = D ( 4 ) , D ( x3 ) D ( y3 ) = D ( 4 ) , (Remember to use the chain rule on D ( y3 ) ) 3 x2 3 y2 y ' = 0 , so that (Now solve for y ' ) 3 y2 y ' = 3 x2 , andIs addition and one when it is subtractionX 3 x 2 yxy 2 x 2 yxy 2 y 3 So to factorize x 3 y 3 you would need to know that you have to add and subtract x 2 y and xy 2 from the expression and factorize from there The geometric technique I mentioned helps you do this without having to guess, it quickly shows you what you must add and subtract in order to factorize the expression

0 Office_Shredder said (xy) 2 = x 2 2xy y 2 >= 0 You know that already So x 2 xy y 2 >= xy If x and y are both positive, the result is trivial If x and y are both negative, the result is also trivial (in both cases, each term in the summation is positive) When one of x or y is negative, xy becomes positive2 x 2 − 2 x y 2 y 2 = ( x − y) 2 x 2 y 2 Again, we have a sum of squares on the right, and this can be 0 only if x, y (and therefore x − y) are all 0 Much more mechanically, we can use the Quadratic Formula For any fixed y, the solutions of x 2 − x y y 2 = 0 are x = y ±Steps for Solving Linear Equation xy=xy x y = x y Subtract xy from both sides Subtract x y from both sides xyxy=0 x y − x y = 0 Subtract y from both sides Anything subtracted from zero gives its negation
