Answer:
step-1.
(a-2b+c)^3=a^3-8b^3+c^3+3ac^2-12abc-6bc^2+12b^2c+3a^2c-6a^2b+12ab^2 समीकरण(1)
step-2.(a-2b)^3)=a^3-8b^3-6ab(a-2b)=a^3-8b^3-6a^2b+12ab^2 समीकरण(2)
step-3.
3c(a-2b+c)(a-2b)=3a^2c-6abc-6abc+12b^2c+3ac^2-6bc^2 समीकरण(3)
समीकरण (1) (2) व (3) को प्रशन मे रखने पर
स्वयं रख कर देखे कुछ जोड़े कट जायेंगे जो बचेगा वो है
step-4.
c^3+6bc^2
step-5.
c^2(c+6b) ANS.
