Derive an expression for a³-b³ |
|
Answer» mula is (a-b)³=a³-3a²b+3ab²-b³. You convert it to (a-b)³=a³-3ab(a-b)-b³ for an ILLUSTRATION. You take the drawing of the formula (a+b)³=a³+3a²b+3ab²+b³ from above and REPLACE a by the difference a-b. Then the edges are (a-b)+b with different combinations (on the LEFT).PLZ MARK ME AS BRAINLIEST!!!!!!!!! |
