the least common denominator is 4 x^2
(x+1)/4x
3(x+1)/2x^2
To find the common denominator, find the prime factors of each denominator
4x =2*2*x
2x^2 = 2*x*x
We need to take the greatest number of each term
2: We have two 2's in the first term and one 2 in the second term so we will take two 2's
x: we have one x in the first term and two x's in the second term so we take two x's
common denominator; 2*2*x*x
4x^2
