Step 1  We can simplify the expression u+1+uu+1 by taking LCM of the denominator of the expression , Converting the denominator of each term to the LCM value . Then we can easily add or subtract the fractional form of the terms.  Step 2   First we can write the expression u+1+uu+1 as u1+11+uu+1, then it will be easy to identify the LCM of the denominator.   Here we have the LCM of the denominator is u+1, we have to convert each denominators in the expression to u+1 by multiplying both numerator and denominator by suitable value.   Here we can multiply both numerator and denominator of first two fractions in the expression by u+1, in the third we already have it as denominator.  thus we get  u1×u+1u+1+11×u+1u+1+uu+1=u(u+1)+(u+1)+uu+1  =u2+u+u+1+uu+1  =u2+3u+1u+1  Hence we have  the simplified for u2+3u+1u+1.
