x = $\"sqrt%28x%2B20%29\"$
\n" ); document.write( "square both sides
\n" ); document.write( " $\"x%5E2\"$ = (x+20)
\n" ); document.write( " $\"x%5E2\"$ - x -20 = 0
\n" ); document.write( " $\"x%5E2\"$ -5x +4x - 20 =0
\n" ); document.write( "x(x-5)+4(x-5)= 0
\n" ); document.write( "(x+4)(x-5) = 0
\n" ); document.write( "x = -4 or x = 5
\n" ); document.write( " \n" ); document.write( "
