Hello!

To solve this exercise, we'll follow the same steps as a common subtraction: group the numbers with the same coefficient.

Look:

[tex](2x^2+5)-(4x-3)[/tex]

First, let's remove the parenthesis and change the signal of the second term:

[tex]2x^2+5-4x+3[/tex]

Now let's group the numbers with the same coefficient:

[tex]2x^2+5-4x+3=\boxed{2x^2-4x+8}[/tex]

Answer:

Alternative B.
