Hello,

I ' m studying chemical kinetics and found one mathematical problem.

Please, can you help me ?

I found in book, that the expression 1/(a-x)^{2}(b-x) is decomposed into partial fractions like:Why is wrong next expression? :1/(a-x)^{2}(b-x) = (R_{1}x+R_{2})/(a-x)^{2 }+ R_{3}/(b-x)

1/(a-x)^{2}(b-x) =R_{1}/(a-x) + R_{2}/(a-x)^{2}+ R_{3}/(b-x)

are initial concentrations (>0)

a,b

For sure, I've attached the handwritten text.

Thank you very much for help

Kevin
