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?

  • math -

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

  • math -

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

  • math -

    then it should have been

    18 + 6√6 + 6√6 + 12
    = 30 + 12√6

  • math -

    did it have an X in it?

  • math -

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