Answer:

A and D are the answer.

Step-by-step explanation:

We can factor this by grouping

[tex]2 {x}^{2} + 5x - 3[/tex]

[tex]2 {x}^{2} + 6x - x - 3[/tex]

[tex]2x(x + 3) -1 (x + 3)[/tex]

The roots are

[tex](x + 3) = 0[/tex]

and

[tex]2x - 1 = 0[/tex]

Let solve for zero in each roots.

[tex]x = - 3[/tex]

[tex]2x = 1[/tex]

[tex]x = \frac{1}{2} [/tex]
