use foil or just plain distribute

if you want foil

FOIL
First
Outer
Inner
Last
that is order to multiply dem numbers

(x+6)(x-4)
First: x times x=x²
Outer: x times -4=-4x
Inner: 6 times x=6x
Last: 6 times -4=-24

add them all together

x²-4x+6x-24
x²+2x-24

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!
