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

@Suradnyana Wisnawa I think the mistake is in the fifth row, where both side divided by (L-2) which is zero Suradnyana Wisnawa · 3 years, 2 months ago
