B is the answer

Answer:

Option B is correct

[tex]2d^2+6d-7[/tex]

Step-by-step explanation:

Difference states that subtracting one number from another.

We have to find the correct difference.

[tex]5d^2 + 4d-3[/tex] less [tex]3d^2-2d+4[/tex]

then;

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

Using distributive property i.e [tex]a \cdot (b+c) = a\cdot b+ a\cdot c[/tex]

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

Combine like terms;

[tex]2d^2+6d-7[/tex]

Therefore, the correct difference is, [tex]2d^2+6d-7[/tex]
