$4 {x}^{2} + 3x - 2$

By using quadratic formula,

$\boxed{ \fbox{ \purple {\frac{b {}^{2} + - \sqrt{ {b}^{2} - 4ac} }{2a} }}}$

$\bf \: x = \frac{ - 3 + - \sqrt{3 {}^{2} - 4 \times 4( - 2) } }{2 \times 4}$

$\bf \: x = \frac{ - 3 + - \sqrt{9 + 32} }{8}$

$\bf \: x = \frac{ - 3 + - \sqrt{41} }{8}$

${ \boxed{ \bf{x = \frac{ \sqrt{41} - 3}{8}}}}$,or $\bf{ \boxed{x = \frac{ - \sqrt{41} - 3 }{8}}}$
