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! :)
Any insight on this next one?
I am not sure why but i get the answer
I was thinking the ^0 multiplies everything to 0 but the 9.
(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!
