Given the trinomial square x^2-8x=4 solve for the solutions of x using the completing square method.
\n" ); document.write( "------
\n" ); document.write( "x^2-8x = 4
\n" ); document.write( "-----
\n" ); document.write( "x^2 -8x + 16 = 4+16
\n" ); document.write( "-----
\n" ); document.write( "Factor:
\n" ); document.write( "(x-4)^2 = 20
\n" ); document.write( "--------
\n" ); document.write( "x-4 = 2sqrt(5) or x-4 = -2sqrt(5)
\n" ); document.write( "--------
\n" ); document.write( "x = 4+2sqrt(5) or x = 4-2sqrt(5)
