Very simple emaths qn

Simplify the following, giving ur ans in positive indices

(1-x) / [1-x^(1/2)]

i suddenly forget how to do Confused

Damn.... I lost touch on my maths le Crying or Very sad

(1-x) / [1-x^(1/2)] * [(1+x^(1/2))/(1+x^(1/2))]
=(1-x)[(1+x^(1/2))/[1-x]
=1+x^(1/2)

using the identity a^2-b^2=(a-b)(a+b)

thanks Very Happy

Or you can separate the top to

(1+x^(1/2))/(1-x^(1/2))

1+x^½ Mr. Green
