Question

factories r^3(s-t)^3+s^3(t-r)^3+t^3(r-s)^3



please solve it urgent need please solve properly do it fast​

Answer 1

Answer:

r(s-t) + s(t-r) + t(r-s)

=rs -rt +st -sr +tr -ts

=0

∵a+b+c= 0

∴a³+b³+c³ = 3abc

r³(s-t)³ +s³(t-r)³ +t³(r-s)³ = 3[r(s-t)][s(t-r)][t(r-s)]

=3rst(s-t)(t-r)(r-s
