Simplify if possible
(i) %28t%5E2%2B3t-18%29+%2F+%28t%5E2%2B12t%2B36%29
first we factor the numerator and denominator to get
(ii) %28%28t%2B6%29%28t-3%29%29+%2F+%28%28t%2B6%29%28t%2B6%29%29
next we cancel the t+6 binomial to get
(iii) %28t-3%29+%2F+%28t%2B6%29

not sure on this one???

Mult. and Simp. if possible.
%28x%5E2-12x%2B20%29%2F%28x%5E7%29 * 5x%2F%28x-10%29
factor all parts that you can to get
%28%28x-2%29%28x-10%29%29%2F%28x%5E7%29 * 5x%2F%28x-10%29
cancel x-10 binomial and then an x to get
%28x-2%29%2F%28x%5E6%29 * 5
answer is
%285x-10%29%2Fx%5E6
