Option b is the correct option

Step-by-step explanation:

we know,

[tex]a - ( - b) = a + b[/tex]

So, from the question given above,

we have to subtract

[tex]2 {x}^{2} - x[/tex]

from

[tex]2x - {x}^{2} [/tex]

so, evaluating this we have,

[tex]2x - {x}^{2} - (2 {x}^{2} - x)[/tex]

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

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

or

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