\"+++sqrt%28+X%2B7+%29+%2B5=X++\"
\n" ); document.write( " \"+++sqrt%28+X%2B7+%29+=+X+-5%29++\" Squaring Both Sides of the EQ
\n" ); document.write( "x + 7 = (x-5)^2
\n" ); document.write( "x + 7 = x^2 - 10x + 25
\n" ); document.write( "x^2 - 11x + 18 = 0
\n" ); document.write( "(x - 9)(x - 2) = 0
\n" ); document.write( "x = 2 , 9
\n" ); document.write( "whenever there is a √ or log involved, for ex., one needs to check to see if both solutions work
