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

According to me 5th step is absolutely right but when you do the 2nd step you must mention l is not equal to 1 · 1 year, 7 months ago

Fifth row, (L-2)=0 · 2 years, 8 months ago

I think the mistake is in the fifth row, where both side divided by (L-2) which is zero · 2 years, 8 months ago

Fifth St ep is wrongg · 2 years, 4 months ago

Simple because of multiplying it by (L-1) it become quadratic ..So it has two solutions 1 & 2. · 2 years, 8 months ago

after 5th step do L^2-3L+2=0 and get L=2 · 2 years, 8 months ago

2L-2 is 0 · 2 years, 8 months ago

No, 2L-2 = 2 · 2 years, 8 months ago

or 2 · 2 years, 8 months ago

fourth row. · 2 years, 8 months ago
