Question

2x^2+4x+3= 0 by factoisation

Answer 1

Hello friend,

Here is the best answer

$2 {x}^{2} + 4x + 3 = 0$
$d = {b}^{2} - 4ac$
$= {4}^{2} - 4(2)(3)$
$= 16 - 24$
$= - 8$

$= \: d \: \: is \: \: negetive$
roots are not real
$x = \frac{ - b \binom{ + }{ - } \sqrt{d} }{2a}$
$x = \frac{ - 4 \binom{ + }{ - } \sqrt{ - 8} }{2}$
$x = - 2 \binom{ + }{ - } \sqrt{2} \sqrt{ - 1}$
