25 c help me to solve​

Answer»

Answer:

\frac{a}{b}  =  \frac{b}{<klux>C</klux>}  = k (constant) \\ a = bk = c {k}^{2}   \\ b = ck

L.H.S= (a+b+c)(a-b+c)

=(ck²+ck+c)(ck²-ck+c)

= c(k²+k+1)c(k²-k+1)

=c²{(k²+1)²-k²}[As the a²-b²=(a+b)(a-b)]

=c²{k⁴+2k²+1-k²}

=c²(k⁴+k²+1)

R.H.S=a²+b²+c²

=c²k⁴+c²k²+c²

=c²(k⁴+k²+1)

L.H.S=R.H.S(Proved)

Here you can see my PROCESS these math has SOLVED.
