Answer 2

Given

$\sf \: 3x²+2x-7=0$

$\sf \: Now \: using \: the \: Formula$

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

Here a=3 , b= 2 , c= -7

$\sf \: x = \frac{ - 2 \pm \: \sqrt{ 4 + 84} }{6}$

$\sf \: x = \frac{ - 2 \pm \: \sqrt{ 88} }{6}$

$\sf \: x = \frac{ - 2 \pm \: 2 \sqrt{22} }{6}$

$\sf \: x = \frac{ - 1 \pm \: \sqrt{22} }{3}$
