Write the following equation in standard form, then identify the type of conic and graph:
\n" ); document.write( "x^2+20x-4y+100=0
\n" ); document.write( "complete the square:
\n" ); document.write( "(x^2+20x+100)-100-4y+100=0
\n" ); document.write( "(x+10)^2-4y=0
\n" ); document.write( "(x+10)^2=4y
\n" ); document.write( "This is an equation of a parabola with vertex at (-10,0)
\n" ); document.write( "see graph below:\r
\n" ); document.write( "\n" ); document.write( " $\"+graph%28+300%2C+300%2C+-20%2C+5%2C+-10%2C+10%2C+%28x%2B10%29%5E2%2F4%29+\"$ \n" ); document.write( "
