checking problem
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

Thats right! :)

Thankyou.
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. 
John,
(anything) = 1 except 0^0 which is undefined 
Anything 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! 
6xy/9y4x30x3y/48x

5(x+1)+3x+2=6x+4
