Answer:

Option C

Step-by-step explanation:

The complete question is in the attachment.

The given equation is

[tex]2 {x}^{2} - 9x + 2 = - 1[/tex]

We rewrite in standard form to get;

[tex]2 {x}^{2} - 9x + 3 = 0[/tex]

Compare to

[tex]a {x}^{2} + bx + c = 0[/tex]

we have a=2, b=-9 and c=3.

We substitute into the formula for the discriminant:

[tex]D= {b}^{2} - 4ac[/tex]

We substitute to get:

[tex]D= {( - 9)}^{2} - 4 \times 2 \times 3[/tex]

[tex]D=81- 24 = 57[/tex]

Since the discriminant is greater than zero, there are two real roots.
