Put this conic section into standard form. What is the a^2 value?
\n" ); document.write( "25x^2 + 16y^2 + 150x = 160y - 225
\n" ); document.write( "complete the square
\n" ); document.write( "25x^2+150x+16y^2-160y = -225
\n" ); document.write( "25(x^2+6x+9)+16(y^2-10y+25) = -225+225+400
\n" ); document.write( "\"%28x%2B3%29%5E2%2F16%2B%28y-5%29%5E2%2F25=1\"
\n" ); document.write( "This is an equation of an ellipse with vertical transverse axis.
\n" ); document.write( "Its standard form: \"%28x-h%29%5E2%2Fb%5E2%2B%28y-k%29%5E2%2Fa%5E2=1\" , (h,k)=(x,y) coordinates of center
\n" ); document.write( "a^2=25
\n" ); document.write( "
\n" );
