Question

How do I solve this, pretty urgent please. ​

Answer 1

• 1

Explanation:

Substitute:

• 
  `x^(0.5) = y`

Then the expression becomes:

• 
  `((1+y^3)/(1-y+y^2)-y) (1-y^2)/(1-y) -y=\\`
• 
  `(((1+y)(1-y+y^2))/(1-y+y^2)-y) ((1-y)(1+y))/(1-y) -y=`
• 
  `(1+y-y)(1+y)-y=`
• 
  `1(1+y)-y=`
• 
  `1+y-y=`
• 1

The result is 1 regardless the value of x other than 1.
