$\sf Hello!$

$\sf y = 2x^{2} + 4x - 3$

$\sf Discriminant$ :

= $\sf b^{2} - 4ac$

= $\sf (4)^{2} - 4.(2).(-3)$

= $\sf 16 - (-24)$

= $\sf 16 + 24$ = $\sf 40$

$\sf Since,$
$\sf D \:is\:Greater\: than\: 0.$

$\sf Roots\: are\: Real\: and\: Distinct$

$\sf Hence,$

$\sf y = 2x^{2} + 4x - 3\: have\: A.\: Two\: real\: roots$
