The standard form is $\"y=ax%5E2%2Bbx%2Bc\"$
\n" ); document.write( "Use the formula $\"%28a%2Bb%29%5E2=a%5E2%2B2ab%2Bb%5E2\"$
\n" ); document.write( " $\"y=2%28x%5E2%2B8x%2B16%29-21\"$
\n" ); document.write( "Open the brackets
\n" ); document.write( " $\"y=2x%5E2%2B16x%2B32-21\"$
\n" ); document.write( " $\"y=2x%5E2%2B16x%2B11\"$
\n" ); document.write( "Answer: $\"y=2x%5E2%2B16x%2B11\"$ \n" ); document.write( "
