nahi bhai aisi baat nahi ha i
.......... below i am posting the same qn if u get the ans plz reveal the method
bhai ye qn kal ke railway ke section engineer ke paper mein aaya tha..maine qn note kiya lekin opn nahi........so sorry...........isi section mein 2 qn thaa... first to maine pahle hi post kar diya hai....second wala bhi put karta hoon...
if x = (root3 + 1)/2
then
4x^3+2x^2 - 8x + 7 is....

bhai kisi ne kaha tha ki x^3 and x^2 ki value nikal lo aur equation mein put kar do but if there is a faster way then do lemme noe....

main bhi ek gaana sun raha hun..............ye duniya ye mehfil mere kaam ki nahi

for everybody's info this particular song was composed,written,sung n even the guitar all played by the versatile aayushman khurana

bhai it will be lengthy...........agar iska factorisation kar de to ans chota ho jaayega.....mere hisab se hardly 3 - 4 line ka ans hona chahiye

Ans is 10 .... my take
if x = 3 then ( x^4 - 13x^2 + 36 ) = ?
