Solutions

Chapter 1.4, Problem 90E
To determine

To calculate: The expression by rationalization xx+hhxx+h

Expert Solution

Answer to Problem 90E

  xx+hhxx+h=1x(x+h)(x+x+h)

Explanation of Solution

Given information:

Given expression is xx+hhxx+h

Consider the expression as xx+hhxx+h

Now,

  xx+hhxx+h=xx+hhxx+h×x+x+hx+x+h=(x)2(x+h)2hx(x+h)(x+x+h)=xxhhx(x+h)(x+x+h)=1x(x+h)(x+x+h)

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