Answer:

ɑ/b+b/ɑ+b/c+c/b+c/ɑ+ɑ/c+3

=(ɑ^2+b^2) /ɑb+(b^2+c^2) /bc+(c^2+ɑ^2) /cɑ+3

=(cɑ^2+cb^2+ɑb^2+ɑc^2+bc^2+bɑ^2+3ɑbc) /ɑbc

={ɑ^2(c+b+ɑ-ɑ) +b^2(c+ɑ+b-b) +c^2(ɑ+b+c-c) +3ɑbc}/ɑbc

={(ɑ+b+c) (ɑ^2+b^2+c^2) -(ɑ^3+b^3+c^3–3ɑbc) }/ɑbc

={(ɑ+b+c) (ɑ^2+b^2+c^2-ɑ^2-b^2-c^2+ɑb+bc+cɑ) })/ɑbc

={(ɑ+b+c) (ɑb+bc+cɑ) }/ɑbc

=(ɑ+b+c) (1/c+1/ɑ+1/b)

=(ɑ+b+c) (1/ɑ+1/b+1/c)…… reɑd fɑctorisɑtion
