You can put this solution on YOUR website!
(1 - x)^2 = 4
\n" ); document.write( " Square root both sides
\n" ); document.write( " 1 - x = sqrt4
\n" ); document.write( " 1 - x = 2
\n" ); document.write( " - x = 2 - 1
\n" ); document.write( " - x = 1
\n" ); document.write( " x = -1
\n" ); document.write( "Proof
\n" ); document.write( "(1 - x)^2 = 4
\n" ); document.write( "(1 - (-1)^2 = 4
\n" ); document.write( " (1 + 1)^2 = 4
\n" ); document.write( " (2)^2 = 4
\n" ); document.write( " 4 = 4
\n" ); document.write( "Hope this helps.
