Question

Can someone help and explain ? thank you !

Answer 1

`\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`
