Factor is much as you can:
1)
1%2F%28%286x%5E2-11x%2B3%29%29 + 1%2F%28%288x%5E2-18%29%29 = 1%2F%28%282x-3%29%283x-1%29%29 + 1%2F%282%284x%5E2-9%29%29 = 1%2F%28%282x-3%29%283x-1%29%29 + 1%2F%282%282x-3%29%282x%2B3%29%29
:
the common denominator will be: 2(2x-3)(3x-1)(2x+3)
:
%282%282x%2B3%29%2B%283x-1%29%29%2F%282%282x-3%29%283x-1%29%282x%2B3%29%29 = %284x+%2B+6+%2B+3x+-+1%29%2F%282%282x-3%29%283x-1%29%282x%2B3%29%29 = %287x+%2B+5%29%2F%282%282x-3%29%283x-1%29%282x%2B3%29%29
:
:
2)
%284r%29%2F%28%28r-2%29%29 + %284r%29%2F%28%28r%2B2%29%29 = %28%284r%29%28r%2B2%29+%2B+%284r%29%28r-2%29%29%2F%28%28r%2B2%29%28r-2%29%29 = %284r%5E2+%2B+8r+%2B+4r%5E2+-+8r%29%2F%28%28r%2B2%29%28r-2%29%29 = %288r%5E2%29%2F%28%28r%2B2%29%28r-2%29%29 or %288r%5E2%29%2F%28r%5E2+-+4%29
