Solve square root <br> X^2+12x+43=0

AlekseyPX

$x^2+12x+43=0
$

$x= \dfrac{-b+ \sqrt{b^2-4ac} }{2a}, \dfrac{-b- \sqrt{b^2-4ac} }{2a}$

$x= \dfrac{-12+ \sqrt{12^2-4*43} }{2}$ , $\dfrac{-12- \sqrt{12^2-4*43} }{2}$

$x= \dfrac{-12+2 \sqrt{7i} }{2}, \dfrac{-12-2 \sqrt{7i} }{2}$

$x=-6+ \sqrt{7i},-6- \sqrt{7i}$
