If determinant p b c
a q c =0 ,find the value of a/(p - a)+b/(q - b)+r/(r - c) ,(p!=a,q!=b,r!=c).
a b r
Help me soon .Thank you

the given determinant is:
pbcaqcabr=0 applying R1R1-R2 and R2R2-R3(p-a)(b-q)00(q-b)(c-r)abr=0applying C1C1p-a;C2C2q-b;C3C3r-c(p-a)(q-b)(r-c)1-1001-1a(p-a)bq-brr-c=0, since pa;qb and rc
1-1001-1a(p-a)bq-brr-c=0now expanding the determinant:rr-c+bq-b-1.-ap-a=0ap-a+bq-b+rr-c=0

hope this helps you
