What is x + yplease help me

1.	What is x + yplease help me
Answer» ong>Answer: 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). Step-by-step explanation: (x,y) has the meaning of plane's point COORDINATES. The first x is the horizontal coodinate (abscisa) and second is the vertical coordinate (ordenate). Both are coordinates. (x,y) has the meaning of a COMPLEX number: x is the real part and y is the imaginary part: x+yi.
