\n" ); document.write( "Hi,
\n" ); document.write( "solving the following using the Quadratic formula
\n" ); document.write( "3x^2-48=0 Note b = 0, in this example
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "\"x+=+%280+%2B-+sqrt%28+576+%29%29%2F%286%29+\"
\n" ); document.write( "\"x+=+%280+%2B-+24%29%2F%286%29+\"
\n" ); document.write( " x = ± 4\r
\n" ); document.write( "\n" ); document.write( "Note: Solving by factoring
\n" ); document.write( "3x^2-48=0
\n" ); document.write( "3(x^2-16)=0
\n" ); document.write( "3(x-4)(x+4)=0
\n" ); document.write( "(x-4)=0
\n" ); document.write( " x = 4
\n" ); document.write( "(x+4)= 0
\n" ); document.write( " x = -4 \n" ); document.write( "
\n" );
