    Answer:

    4a^2+9b^2+12ab-(9a^2+4b^2-12ab)

    4a^2+9b^2+12ab-9a^2-4b^2+12ab

    -5a^2+5b^2+24ab

    -5(a^2+b^2)24ab

    Answer:

     {(2a + 3b)}^{2}  -  {(3a - 2b)}^{2}

    ({(2a)}^{2}+2.2a.3b+{(3b)}^{2}) - (( {3a)}^{2} - 2.3a.2b +  {(2b)}^{2}  )

    ({4a}^{2}+12ab+{9b}^{2}) - (9 {a}^{2} - 12ab +  {4b}^{2}   )

    {4a}^{2}+12ab+{9b}^{2}-{9a}^{2} + 12ab - {4b}^{2}

     { - 5a}^{2} +  {5b}^{2} + 24ab

     -5 ({a}^2-{b}^2)+24ab

     -5 [(a+b)(a-b)]+24ab
