Answer:

Given equation is

          4x^2+12xy +9y^2

Also given,

         x=\frac{5}{2}

         y=\frac{2}{3}

4x^2+12xy +9y^2 = 4(\frac{5}{2} )^2+12*\frac{5}{2} *\frac{2}{3} +9(\frac{2}{3} )^2

                              = 4*\frac{25}{4} +12*\frac{5}{3} +9*\frac{4}{9}

                              = 25+20+4

                              = 49

                Hope it helps you^_^
