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!
