Hello, all,

I am here is to ask how can I factorise an equation with fraction indeces?? (Help~)

The question I have got is x^(3/2) + a^(3/2), and the suggested method is using the factor theorem... but I just don't understand how could that works...

However, I would be very grateful if somebody could give me a hint~

Thanks
