kay, so i have made the all of the denominator (3x-12)(x-4), the i have to multiplied (2x+2)(x-4),after adding and subtracting i got -2x^2-11x-19 = 0 , which i think is wrong, since it wouldnt work in the quadratic formula //first question answers are suppose to be 1 and -13.

Thankks i got the answer. but what about for the second question. cause i only knew that k^2 +8k +12 = (k+2)(k+6) .. so the lcd cant possibly be (k-2)(k-6)(k+2)(k+6) lool...
