Question

17 x square y square -34 x y cube.

Answer 1

Step-by-step explanation:

The formula is (x-y)³=x³-3x²y+3xy²-y³. You convert it to (x-y)³=x³-3xy(x-y)-y³ for an illustration. ... You take the drawing of the formula (x+y)³=x³+3x²y+3xy²+y³ from above and replace a by the difference x-y. Then the edges are (x-y)+y with different combinations (on the left)...
