5x^2-2x=7
\n" ); document.write( "Divide by 5 to make the coefficient of x^2 = 1
\n" ); document.write( "\"x%5E2+-+%282%2F5%29x+=+7%2F5\"
\n" ); document.write( "a = 1, b = -2/5
\n" ); document.write( "Add (b/2)^2 = 1/25
\n" ); document.write( "\"x%5E2+-+%282%2F5%29x+%2B1%2F25+=+7%2F5+%2B+1%2F25\"\r
