The difference between two cubed values can be expanded by using the difference of two cubes formula. This expansion would be as follows: $$x^3 - y^3 = \left(x-y\right) \left(x^2 + xy + y^2 \right) $$ This formula may be used in the factorization of polynomials. Answer ...
The difference of x and y is positive if and only if x is greater than y . 注意:less 和 lesser (not so great or important as the other or the rest) 不同;If there are two numbers x<y , the lesser one is x and the greater one is y ; we say x is less than y or y is ...
x3 + y3 = (x + y)(x2 − xy + y2) [Sum of two cubes] x3 − y3 = (x − y)(x2 + xy + y2) [Difference of 2 cubes]Where do these come from? If you multiply out the right side of each, you'll get the left side of the equation....
