Answer 2

$\sf given \: \: quadratic \: \: \: eq^{n} \: : \\ \sf 3 {x}^{2} + 5x + 7$

$\sf to \: \: \: \: solve \: : \: \boxed{ \rm x}$

$\color{lime}\mathfrak{SOLUTION} \: : \:$

By using Quadratic Formula,

$\boxed{ \color{yellow} \rm x = \frac{ - b \: \pm \: \sqrt{ {b}^{2} - 4ac } }{2a} }$

then,

$\rm \: x = \frac{ - 5 \: \pm \: \sqrt{ {(5)}^{2} - 4(3)(7) } }{2(3)}$

$\rm \: x = \frac{ - 5 \: \pm \: \sqrt{25 - 84} }{6}$

$\rm \: x = \frac{ - 5 \pm \sqrt{ - 59} }{6}$

$\sf hence \: \: \: roots \: \: \: \: are \\ \sf \boxed{ \orange{\sf \frac{ - 5 + \sqrt{ - 59} }{6} }} , \boxed{ \pink{\sf\frac{ - 5 - \sqrt{59} }{6}} }$
