document.write( "If I am understanding Your question properly:
\n" );
document.write( "   |squaring both sides of the Eq
\n" );
document.write( " 7x + 36 = (x+4)^2
\n" );
document.write( " 7x + 36 = x^2 + 8x + 16
\n" );
document.write( "   x^2 + x - 20 = 0
\n" );
document.write( " (x+5)(x-4)=0 Note:SUM of the inner product(5x) and the outer product(-4x) = x
\n" );
document.write( " (x+5)=0  x = -5  |Extraneous solution sqrt(1) ≠ -1
\n" );
document.write( " (x-4)=0  x = 4 \n" );
document.write( "

\n" );
