From the question before, I got to 18+6*SQRT5+6*SQRT5+12 am I on the right track or did I make a mistake somwhere?

Did you foil correctly? I'm not sure what your equation is.

(3*SQRT2+2*SQRT3)(3*SQRT2+2*SQRT3)
Does this help?

then it should have been

18 + 6√6 + 6√6 + 12
= 30 + 12√6

did it have an X in it?

No there was no X, but I accidentally did 2+3 instead of 2*3. Just a dumb mistake. Thanks.
