Write the following in standard form and name the conic section.
\n" ); document.write( "1. x^2+6x-3y+15=0
\n" ); document.write( "x^2+6x +9 = 3y-15 + 9
\n" ); document.write( "(x+3)^2 = 3y-6
\n" ); document.write( "3(y-2) = (x+3)^2
\n" ); document.write( "y = (1/3)(x^3)^2+2
\n" ); document.write( "----
\n" ); document.write( "Parabola opening upward from (-3,2)
\n" ); document.write( "==========================================\r
\n" ); document.write( "\n" ); document.write( "2. x^2+y^2-2x+2y-7=0
\n" ); document.write( "(x^2-2x+1) + (y^2+2y+1) = 7 + 1 + 1
\n" ); document.write( "(x-1)^2 + (y+1)^2 = 9
\n" ); document.write( "Circle with center at (1,-1) and radius = 3
\n" ); document.write( "===========================================
\n" ); document.write( "and
\n" ); document.write( "3. x^2-6x+9+y^2-18y+81=36
\n" ); document.write( "x^2-6x+9 + y^2-18y+81 = 36
\n" ); document.write( "(x-3)^2 + (y-9)^2 = 36
\n" ); document.write( "Circle with center at (3,9) and radius = 6
\n" ); document.write( "==============================================
