Answer:

Option D: 3x2 + 2x - 1

Step-by-step explanation:

Given that:

=(5x2 - 5x + 3 )- (2x2 +7x- 4)

As we have to subtract them so by simplifying:

"-" sign will alter all signs in the bracket

= 5x2 - 5x + 3 - 2x2 + 7x - 4

Now by adding same terms

= 5x2 - 2x2 - 5x + 7x + 3 -4

= 3x2 + 2x - 1

i hope it will help you!
