Question

if alpha and beta are the zero of the polynomial x^2 + x + 1 then find 1/alpha 1/beta ?​

Answer 1

Answer:

1

Step-by-step explanation:

  $x^2 +x+1=0\\comparing  with\\ax^2+bx+c=0\\a=1;b=1;c=1;\\then\\\alpha +\beta =\frac{-b}{a} =-1\\\alpha \beta =\frac{c}{a} =1\\\frac{1}{\alpha \beta } =\frac{1}{1} =1$
