solve the quadratic equation by completing the square.\r
\n" ); document.write( "\n" ); document.write( "\"2p%5E2=6p-20\"
\n" ); document.write( "\"2p%5E2=6p%2F2-20%2F2\" First divide everything by the coefficient of p^2
\n" ); document.write( "\"p%5E2=3p-10\" The put the p^2 and p on one side and the constant on the other.
\n" ); document.write( "\"p%5E2-3p=-10\"
\n" ); document.write( "\"p%5E2-3p%2B9%2F4=-10%2B9%2F4\" (1/2 the coefficient of p) suqred is added to both sides.
\n" ); document.write( "\"%28p-3%2F2%29%5E2=-40%2F4%2B9%2F4\" Factor your perfect square, the second term is half the coefficient of p.
\n" ); document.write( "\"%28p-3%2F2%29%5E2=-31%2F4\"
\n" ); document.write( "\"sqrt%28%28p-3%2F2%29%5E2%29=%2B-sqrt%28-31%2F4%29\" take the square root of both sides
\n" ); document.write( "\"p-3%2F2=%2B-sqrt%2831%29i%2F2\" The suqare root of -1 is i.
\n" ); document.write( "\"p=3%2F2%2B-sqrt%2831%29i%2F2\"
