To calculate: The expression x2y2x1+y1

Expert Solution

Answer to Problem 65E

  x2y2x1+y1=yxxy

Explanation of Solution

Given information:

Given expression is x2y2x1+y1

Consider the expression as x2y2x1+y1

Now,

  x2y2x1+y1=1x21y21x+1y=y2x2x2y2y+xxy=xy(y2x2)x2y2(y+x)=(y+x)(yx)xy(y+x)=yxxy

Therefore, simplest form of the expression x2y2x1+y1=yxxy
