Answer 2

Answer:

HEY MATE HERE'S YOUR ANSWER

Step-by-step explanation:

$</p><p></p><p>f(x)=x2+x+1 \\ a=1 \\ b=1 \\ c=1 \\ ∵α \: and \: β \: are \: the \: zeroes \: of \: above \: polynomial. \\ ∴ Sum \: of \: roots =a−b \\ ⇒α+β=1−1 \\ ⇒α+β=−1⟶(1) \\ Product \: of \: roots =ac \\ ⇒αβ=11 \\ ⇒αβ=1⟶(2) \\ ∴α1+β1=αββ+α \\ From \: eqn(1)(2), we \: have \\ ⇒α1+β1=1−1=−1 \\ Hence, \: -1 \: is \: the \: correct \: answer</p><p></p><p>$
