equation in given.
so .A+B=-b/a and A.B=c/a
1/A-1/B=B-A/A.B
=(b square -4a.c)/c
so .A+B=-b/a and A.B=c/a
1/A-1/B=B-A/A.B
=(b square -4a.c)/c

(B-A) square/A.B
AM SORRY ..aage ka answer abhi type kar rha hu.
1/A-1(/B=(B-A)/A.B ={(B-A)/(A.B)}square=(B2+A2-2A.B)/(A.B)2 ={(B+A)2-2AB-2A.B}/A.B2 = {(-b/a)-4c/a}/(c/a)2 ={b2/a2-4c/a}/(c/a)2 = {(b2-4ac)/a2}/c2/a2 =(b2-4ac)/c. ANS, is it correct...!!
