Question

(3ab+9a-2)-(-5ab+4)

Answer 1

To solve this you have to simplify the 2nd polynomial in parathenses

Answer 2

-(-5ab+4) is simplified to 5ab-4, then 3ab+9a-2+5ab-4

Answer 3

I get -2ab+9a+2

Answer 4

That is incorrect because you simplified the binomial wrong, as shown above it is simplified to 5ab-4

Answer 5

With the proper simplification of 5ab-4, what would be the answer?

Answer 6

5ab-9a-4

Answer 7

You have 3ab+5ab+9a-6, 5ab-9a-4 is not correct

Answer 8

5ab-4 isn't correct either, I'm supposed to find the difference of the two polynomials, the answer should be a trinomial
