Select one of the options below as your answer:



A.
-3x2 − 4x




B.
-3x2 + 14x




C.
3x2 − 4x




D.
3x2 + 14x

Answer 1

I think its b ,because the negative sign goes to 3x2 .Also you do 5x+9x which is 14x.

Answer 2

you sure

Answer 3

ITS A -_-

Answer 4

actually its c,because the negative sign applies to the parenthesis which would be 5x--3x2-9x. You then turn those two minus signs into positive signs like this 5x+3x2-9x.Finally you just do 5x-9x which is -4x.
