Solutions

Chapter 1.3, Problem 94E
To determine

To calculate: The factor of the expression x1/2(x+1)1/2+x1/2(x+1)1/2 .

Expert Solution

Answer to Problem 94E

The factor of the expression x1/2(x+1)1/2+x1/2(x+1)1/2 is 1x2+x(2x+1) .

Explanation of Solution

Given information:

The expression x1/2(x+1)1/2+x1/2(x+1)1/2 .

Formula used:

To factor an expression, split the terms in the expression into multiplication of simpler expressions, then take the common power out and group the expressions together.

Calculation:

Consider the given expression x1/2(x+1)1/2+x1/2(x+1)1/2 .

Recall that to factor an expression, split the terms in the expression into multiplication of simpler expressions, then take the common power out and group the expressions together.

The greatest common factor of these terms is x1/2(x+1)1/2 .

Apply it,

  x1/2(x+1)1/2+x1/2(x+1)1/2=x1/2(x+1)1/2[(x+1)1/2(x+1)1/2+x1/2x1/2]=x1/2(x+1)1/2[(x+1)12+12+x12+12]=1xx+1[x+1+x]=1x2+x(2x+1)

Thus, the factor of expression x1/2(x+1)1/2+x1/2(x+1)1/2 is 1x2+x(2x+1) .
