A) 72
B) 192
C) 200
D) 248
Correct Answer: D
Solution :
\[225+{{(3\omega +8{{\omega }^{2}})}^{2}}+{{(3{{\omega }^{2}}+8\omega )}^{2}}\] \[=225+{{(5{{\omega }^{2}}-3)}^{2}}+{{(5\omega -3)}^{2}}\] \[=225+18-5(\omega +{{\omega }^{2}})\] \[=225+18-5(-1)=225+18+5=248.\]You need to login to perform this action.
