x²+x+1=0is A)(2) B)(-3) C)(3) D)(-2)​

Answer 1

so say Me what do you mean by exhaustible and give an example explanation

Answer 2

$\tt We\:know\:that\: discriminant\:of\: equation \\ \tt a{x}^{2} +bx + c = 0 \: is \: given \: by \\ \\ \red{\underline{\tt \Delta = {b}^{2} - 4ac }} \\ \\ \tt Comparing\:tje\:given\: equation\\ \tt with\:standard\:equation \\ \\ \tt a = 1 \\ \tt b = 1 \\ \tt c = 1 \\ \\ \tt \therefore \Delta = {1}^{2} - 4× 1 × 1 \\ \\ \tt \therefore \Delta = 1 - 4 \\ \\ \tt \therefore \boxed{\bold{\underline{\red{\tt \Delta = - 3 }}}}$
