The denominator is missing a * multiplication. Maybe you meant:

[L*C*(R1+R2)*(R1*R2*C + L) R1]

Note the * between the two terms in parentheses.

Or maybe it's missing a space and should be:

[L*C*(R1+R2) (R1*R2*C + L) R1]

If that's the case, it's a good idea to get in the habit of using a comma to separate terms in row vector

[L*C*(R1+R2) , (R1*R2*C + L) , R1]
