To calculate: The expression (1x2)12+x2(1x2)121x2

Expert Solution

Answer to Problem 78E

  (1x2)12+x2(1x2)121x2=1(1x2)32

Explanation of Solution

Given information:

Given expression is (1x2)12+x2(1x2)121x2

Consider the expression as (1x2)12+x2(1x2)121x2

Now,

  (1x2)12+x2(1x2)121x2=1x2+x21x21x2=1x2+x21x21x2=1(1x2)12+1=1(1x2)32

Therefore, simplest form of the expression (1x2)12+x2(1x2)121x2=1(1x2)32
