The first step is to find the square root of both sides of the equation. The square root of x-20 squared is obviously x-20, and the square root of 0 is 0. So,
\n" ); document.write( "x-20=0
\n" ); document.write( "Then, add 20 to both sides.
\n" ); document.write( "x=20
\n" ); document.write( "So, x equals 20. \n" ); document.write( "
