(c+1/c^{2})2

= (c+1/c)(c+1/c)

= c^{2}+1/c^{2}+1/c^{2}+1/c^{4}

=c^{2}+2/c^{2}+1/c^{4 }=c^{6}+2c^{2}+1

(c+1/c

^{2})2

= (c+1/c)(c+1/c)

= c^{2}+1/c^{2}+1/c^{2}+1/c^{4}

=c^{2}+2/c^{2}+1/c^{4 }=c^{6}+2c^{2}+1 - Jun 2nd 2012, 09:33 PMrainbowoblivionRe: Simplify
Are you just wanting someone to double check your work?
