Solutions

Chapter 1.4, Problem 70E
To determine

To calculate: The expression 1x+h1xh

Expert Solution

Answer to Problem 70E

  1x+h1xh=1x(x+h)(x+x+h)

Explanation of Solution

Given information:

Given expression is 1x+h1xh

Consider the expression as 1x+h1xh

Now,

  1x+h1xh=xx+hxx+hh=xx+hhx(x+h)×x+x+hx+x+h=(x)2(x+h)2hx(x+h)(x+x+h)=xxhhx(x+h)(x+x+h)=hhx(x+h)(x+x+h)=1x(x+h)(x+x+h)

Therefore, simplest form of the expression 1x+h1xh=1x(x+h)(x+x+h)
