do anybody have reasons for this??

L = 2

L(L-1) = 2(L-1)

L2-L = 2L-2

L2-2L = L-2

L(L-2) = L-2

L = 1

Find the mistake in the above maths equations

Fifth row, (L-2)=0

I think the mistake is in the fifth row, where both side divided by (L-2) which is zero

According to me 5th step is absolutely right but when you do the 2nd step you must mention l is not equal to 1

No, 2L-2 = 2

Simple because of multiplying it by (L-1) it become quadratic ..So it has two solutions 1 & 2.
