Vedclass · Answer

(D) The given quadratic equation is $-x^{2}+x-2=0$. Comparing this with the standard form $ax^{2}+bx+c=0$,we get $a=-1, b=1, c=-2$. The discriminant $D$ is given by $D = b^{2}-4ac = (1)^{2}-4(-1)(-2) = 1-8 = -7$. The roots are given by the quadratic formula $x = \frac{-b \pm \sqrt{D}}{2a}$. Substituting the values,$x = \frac{-1 \pm \sqrt{-7}}{2(-1)} = \frac{-1 \pm \sqrt{7}i}{-2}$. This can be simplified as $x = \frac{1 \pm \sqrt{7}i}{2}$.

Solve the equation $-x^{2}+x-2=0$.
