Expert Solution

Answer to Problem 43RE

  x1/2(x1)2

Explanation of Solution

Given information:

Factor the expression completely.

  x1/22x1/2+x3/2

Calculation:

Consider the given expression.

  x1/22x1/2+x3/2

Take 1x common from the expression,

  x1/22x1/2+x3/2=1x(12x+x2)

Now apply identity inside parenthesis.

  (ab)2=a2+b22ab

  1x(x1)2=x1/2(x1)2

Hence, the factors are x1/2(x1)2
