Answer 2

Solution:-

given equation:-

$x { }^{2} + 13x + 20 \\ by \: formula \\ \frac{ - b( + - ) \sqrt{ {b}^{2} - 4ac} }{2a} \\ \frac{ - 13( + - ) \sqrt{ {13}^{2} - 4 \times 1 \times 20} }{2 \times 1} \\ \frac{ - 13( + - ) \sqrt{169 - 80} }{2} \\ \frac{ - 13( + - ) \sqrt{89} }{2} \\ x = \frac{ - 13 + \sqrt{89} }{2} \\ x = \frac{ - 13 - \sqrt{89} }{2}$
