Select the correct difference.

5d2 + 4d - 3 less 2d2 - 3d + 4

You can do this piece by piece. Start with the first terms in both expressions.

5d^2 - 2d^2 When two terms have the same variable (in this case d^2), you can act like the variable isn't there. So, treat this like 5 - 2 and then add the variable back on.

3d^2

Now, do the same for the other terms with matching variables. (4d - 3d) and (-3 + 4).

3d^2 + d + 1
