What is the vertex of the parabola given by the equation $\"y=3x%5E2-48x%2B115\"$
\n" ); document.write( "***
\n" ); document.write( "Vertex form of equation: y=A(x-h)^2+k, (h,k)=coordinates of the vertex
\n" ); document.write( "y=3x^2-48x+115
\n" ); document.write( "complete the square:
\n" ); document.write( "y=3(x^2-16x+64)+115-192
\n" ); document.write( "y=3(x-8)^2-77
\n" ); document.write( "vertex: (8,-77) \n" ); document.write( "
