Answer 2

$2 {x}^{2} + x - 4 = 0 \\ a {x}^{2} + bx + c = 0 \\ a = 2 \: \: \: \: \: \: \: b = 1 \: \: \: \: \: c = - 4 \\ \frac{( - b )+ or - \sqrt{ {b}^{2} - 4ac} }{?} \\ \frac{ - 1 + \sqrt{ {( - 1)}^{2} - 4( - 8) } }{2(2)} \\ \frac{ - 1 + \sqrt{1 + 32} }{4} \\ \frac{ - 1 + \sqrt{33} }{4} and \frac{ - 1 - \sqrt{33} }{4} is \: the \: root \: of \: given \: eqution$
