\n" ); document.write( "\n" ); document.write( "\"f%28x%29=%28x%5E2%29%2B14x%2B14\"................complete the square to express the quadratic in standard form\r

\n" ); document.write( "\n" ); document.write( "\"x%5E2%2B14x=-14\".........Take half of the coefficient (don't forget the sign!) of the x-term, and square it. Add this square to both sides of the equation.\r
