Use FOIL to multiply:

(6x – 1)(3x – 4)

6x*3x + 6x*(-4) + (-1)*3x + (-1)*(-4) =

6x*3x = 18x^2

6x*-4 = -24x

-1*3x = -3x

-1* -4 = 4

18x^2 – 24x -3x +4 =

18x^2 – 27x + 4

Any insight on this next one?

(x^4y^6z^12/9^-2x^3y^-8z^-9)^0

I am not sure why but i get the answer

1/9^0

I was thinking the ^0 multiplies everything to 0 but the 9.

(anything) = 1 except 0^0 which is undefined

**Melissa**, Monday, October 22, 2007 at 9:24pmAnything to the 0 power is 1. And somehow my final answer was

xz^3 / 9^-2y^-2

but i really could be wrong, hopefully someone else can help u with this one cause im not positive!
