1. Complete the square to put into vertex form.
\n" ); document.write( " $\"2x%5E2+-x-3=+2%28x%5E2+-%281%2F2%29x%29-3\"$
\n" ); document.write( " $\"2x%5E2+-x-3=+2%28x%5E2+-%281%2F2%29x%2B%281%2F16%29%29-3-%281%2F8%29\"$
\n" ); document.write( " $\"2x%5E2+-x-3=+2%28x-1%2F4%29%5E2-%2825%2F8%29\"$
\n" ); document.write( " $\"A=2\"$
\n" ); document.write( " $\"B=-1%2F4\"$
\n" ); document.write( " $\"C=-25%2F8\"$
\n" ); document.write( "2. From vertex form, the min occurs at the vertex $\"x=1%2F4\"$ .
\n" ); document.write( " $\"ymin=-25%2F8\"$
\n" ); document.write( "
