7x^3 - 25x^2 + 17x - 10

= 7x^2 (x - 3) - 4x^2 + 17x - 10

= 7x^2 (x - 3) - 4x(x - 3) + 5x - 10

[notice that I've already eliminated choices A and B and D]

= 7x^2 (x - 3) - 4x(x-3) + 5(x - 3) + 5.

It's answer C and it checks out!

Sorry I didn't use "synthetic division," I hate it. Plain old long division always works fine.
