A) 4
B) 0
C) - 4
D) None of these
Correct Answer: C
Solution :
\[{{(3+5\omega +3{{\omega }^{2}})}^{2}}+{{(3+3\omega +5{{\omega }^{2}})}^{2}}\] \[={{(3+3\omega +3{{\omega }^{2}}+2\omega )}^{2}}+{{(3+3\omega +3{{\omega }^{2}}+2{{\omega }^{2}})}^{2}}\] \[(1+\omega +{{\omega }^{2}}=0,{{\omega }^{3}}=1)\] \[={{(2\omega )}^{2}}+{{(2{{\omega }^{2}})}^{2}}=4{{\omega }^{2}}+4{{\omega }^{4}}=4(-1)=-4\].You need to login to perform this action.
