\n" ); document.write( " $\"60x-2x%5E2\"$ in the form $\"p-2%28x-q%29%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-2x%5E2%2B60x\"$ .....factor out $\"-2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-2%28x%5E2-30x%29\"$ complete the square\r
\n" ); document.write( "\n" ); document.write( " $\"-2%28x%5E2-30x%2Bq%5E2%29-%28-2%29q%5E2\"$ .....since coefficient in front of $\"x%5E2\"$ is $\"1\"$ and in front of $\"x\"$ is $\"30\"$ ,we know that $\"2%2A1%2Aq=30\"$ ; so, $\"q=15\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"-2%28x%5E2-30x%2B15%5E2%29-%28-2%2915%5E2\"$ \r
