Solve For X:
\n" ); document.write( "\"sqrt%285-x%29=x%2B1+\"
\n" ); document.write( "square both sides
\n" ); document.write( "\"5-+x+=+%28x%2B1%29%5E2\"
\n" ); document.write( "FOIL (x+1)(x+1)
\n" ); document.write( "5 - x = x^2 + 2x + 1
\n" ); document.write( "0 = x^2 + 2x + x + 1 - 5
\n" ); document.write( "A quadratic equation
\n" ); document.write( "x^2 + 3x - 4 = 0
\n" ); document.write( "Factors to
\n" ); document.write( "(x+4)(x-1) = 0
\n" ); document.write( "two solutions
\n" ); document.write( "x = -4, we don't want the square root of a negative number
\n" ); document.write( "therefore
\n" ); document.write( "x = 1 is the only solution
\n" ); document.write( "
\n" );
