6) Simply take half of -12 (the x coefficient) to get -6 and square it to get 36. Now add and subtract this value to get $\"x%5E2-12x%2B36-36\"$ . From here, factor $\"x%5E2-12x%2B36\"$ to get $\"%28x-6%29%5E2\"$ . So $\"x%5E2-12x%2B36-36=%28x-6%29%5E2-36\"$ which means that $\"x%5E2-12x=%28x-6%29%5E2-36\"$ \n" ); document.write( "
