Answer 3

are you given a list of choices?

Answer 4

Addition
Subtraction
Two operations result in the same coefficient
Multiplication

Answer 5

why not see what you get when you do f(x) + g(x), f(x) - g(x), f(x)*g(x)

Answer 6

Addition: 4x+3
Subtraction: -5
Multiplication: -2

Answer 7

So I guess addition?

Answer 8

But wait I got addition and it was marked wrong...

Answer 9

Multiplication: -2 is incorrect

Answer 10

you need to apply the FOIL rule

Answer 11

(2x-1)*(2x+4) = ???

Answer 12

Ohhh: 2(2x-1)(x+2)

Answer 13

So would it be multiplication?

Answer 14

what do you get when you expand out (2x-1)*(2x+4)

Answer 15

2x*2x*-1*4?

Answer 16

no

Answer 17

a table like this may help
