Question

(4x^2-5x-6) +(-5x^2-x-3)=-1x^2-6x-9
Can somone tell me if I got the correct answer?

Answer 1

You are correct. Nice job.

Answer 2

You can also write -1x^2 as -x^2

Answer 3

If the plus between the two parenthseses had been a minus. Would the answer would have been 9x^2-4x-3?

Answer 4

So it's (4x^2-5x-6) -(-5x^2-x-3) instead?

Answer 5

yes

Answer 6

If so, then

(4x^2-5x-6) -(-5x^2-x-3)

simplifies to

9x^2-4x-3

which means you are correct (if my initial assumption is correct)

Answer 7

alright, then you are 100% correct
