Question

multiply (2(root 3)-1)(3(root 3)-2)

Answer 1

answer choices are:
-9root3
16+1root3
13root3
20-7root3

Answer 2

Working:
(2 sqrt3)(3 sqrt3) - 2(2 sqrt 3) - 1 (3 sqrt 3) + (-1)(-2)
6(3) -4sqrt 3 - 3sqrt 3 + 2
18 - 7 sqrt 3 + 2
...

Answer 3

so the fist term is NOT (6(root3)^2?

Answer 4

(6)(3) = 6(root3)^2 :)

Answer 5

so I was right originally?
my second line looks like this right now:
(6(root3))^2-4(root3)-3(root3)+2
am I correct so far?
