{{{4/(x+1) + 3x /(x^2+x)}}}


{{{(4/(x+1))((x^2+x)/(x^2+x)) + (3x /(x^2+x))((x+1)/(x+1))}}}


{{{(4x^2+4x)/((x+1)(x^2+x))+(3x^2+3x)/((x+1)(x^2+x))}}}


{{{(4x^2+4x+3x^2+3x)/((x+1)(x^2+x))}}}


{{{(7x^2+7x)/((x+1)(x^2+x))}}}


{{{(7(x^2+x))/((x+1)(x^2+x))}}}


{{{(7cross((x^2+x)))/((x+1)cross((x^2+x)))}}}
