solve by completing the square:
\n" ); document.write( "7x^2-14x+3=0
\n" ); document.write( "---
\n" ); document.write( "7x^2 - 14x = -3
\n" ); document.write( "---
\n" ); document.write( "7(x^2-2x + ?) = -3 + 7*?
\n" ); document.write( "7(x^2-2x+1) = -3 + 7*1
\n" ); document.write( "7(x-1)^2) = 4
\n" ); document.write( "(x-1)^2 = 4/7
\n" ); document.write( "(x-1) = +/-2/sqrt(7)
\n" ); document.write( "x = 1 +- (2/7)sqrt(7)
