Please show work. There was a negative sign that appeared in the solution and I don't know why.(adsbygoogle = window.adsbygoogle || []).push({});

I know [tex]\sqrt{}(1-X)[/tex] can be rewritten as (1-X)^1/2 and then you use the power rule to integrate but that gives you

(1-x)^3/2

------------

3/2

2(1-X)^3/2

--------------

3

My book shows

-(1-X)^3/2

------------

3/2

instead

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
