Question

sum of the roots x2 +x +12​

Answer 1

Answer :

$\alpha +\beta =-1$

Step-by-step explanation :

Given quadratic eq. is  $x^2+x+12$.

Sum of roots = $\frac{-(coefficient*of*x)}{coefficient*of*x^2} =\frac{-b}{a}$

So sum of roots of  $x^2+x+12$ is $\frac{-1}{1} =-1$

Let the roots be $\alpha,\beta$ .

So sum of roots = $\alpha +\beta =-1$
