    I am not sure what the problem means. BUT

    \text{LCD}(y^2-1,~y-1,~y^2+y)=y(y-1)(y+1)~.

    What does that : between the two terms mean? At a guess I would think a "proportion" which is the same as a division.
    In any case, the first thing you need to do is add the fraction \frac{ay+ 1}{y^2- 1}+ \frac{a}{y- 1}+ \frac{a}{y^2+y}

    As Plato said, the least common denominator is y(y- 1)(y+ 1). Multiply numerator and denominator of the first fraction by y, of the second fraction by y(y+ 1), and of the third fraction by y- 1.
