Someone please please answer these!! ahhh

1) 3-19x-14

2) -x-6

3) -8x+16

Step-by-step explanation:

You can use the box method for each of these problems. Or you can use the "FOIL" method. I'll do one example problem for the FOIL method

For the last problem, expand the equation by writing

(x-4)(x-4)

Now you can FOIL the two values

First: x · x=

Outside: x · -4= -4x

Inside: -4 · x= -4x

Last: -4 · -4= 16

Now put all these values together

-4x-4x=16

Now we can combine like terms ( -4x and -4x) to get -8x which we will put back into the equation

So we get

-8x+16 which is your answer

You can use this method anytime you are multiplying polynomials.
