Answer:
(x-12)(x+7)
Step-by-step explanation:
x^2 - 5x - 84
You find the factors of 84:
1,84; 2,42; 3,28; 4,21; 6,14; 7,12
7 and 12 are 5 apart, so we use them:
(x - 12)(x + 7)
The 12 is negative because it's greater than 7, and the coefficient of x is negative 5.

Answer:
The top one is right
Step-by-step explanation:
Because mp3 has to have the most while none has to have the least
To do this, you use the FOIL method.
F: front
x*x=x^2
O: outer
x*-4=-4x
I: inner
6*x=6x
L: last
6*-4=-24
Add all those up and you get:
x^2-4x+6x-24
Which is equal to:
x^2+2x-24
Hope this helped!
