use of symbolic toolbox for the inverse of a matrix

[george brida]

Dear Octavers,
I have the following matrix A:
A(1,1)=T ;  A(1,2)=T*(T+1)/2  ;  
A(2,1)=T*(T+1)/2 ; A(2,2)= T*(T+1)*(2*T+1)/6

I would like to find the inverse of this matrix in this general form.
Can you please help me,
thank you in advance.
George.
