Question

Solve or Simplify (x+y-1)³.

Answer 1

Answer:

x³+3x²y+2xy²-x²-2xy

Step-by-step explanation:

1:(x+y-1)²×(x+y-1)=(x+y-1)×(x+y-1)×(x+y-1)

2: Let's solve the first one:

(x+y+1)²=x²+2(x)(y)×(-1)²=x²+2xy

3:(x²+2xy)×(x+y-1)=x²(x+y-1)+2xy(x+y-1)

=x³+x²y-x²+2x²y+2xy²-2xy=x³+3x²y+2xy²-x²-2xy
