Answer 2

Hello Dear Brainly user...

Question:-

is to find roots of equation

x² + 3x + 9 = 0

Solution :-

By Formula

$x = \frac{ - b± \: \sqrt{ {b}^{2} - 4ac} }{2a}$

Here;

a = 1 , b = 3 & C = 9

Using Formula;

$= > x = \frac{ - 3± \sqrt{ {3}^{2} - 4 \times 1 \times 9 } }{2 \times 1}$

$= >x = \frac{ - 3± \sqrt{9 - 36} }{2}$

$= > x = \frac{ - 3± \sqrt{ - 27} }{2}$

$= > x = \frac{ - 3± 3\sqrt{3} i}{2} \: \: answer$

Hope it helps ✴️ :-)
