Question 1047295
While seeing your original EXPRESSION under you message, a guess is made about what you really have:


(p+1)/(p^2-49)+(p-1)/(p^2+10p+21)


Put between the rendering tag brackets,
{{{(p+1)/(p^2-49)+(p-1)/(p^2+10p+21)}}}


Your earlier-learned skills with fractions are still valid here.
