Our current assignment is to find the LCM, Least Common Multiple of two polynomials. I think I'm doing it right but I'm not quite sure. For the first question:
I have 2t^2+t+3 as the LCM. Is this correct or can somebody step me through the correct method to complete the problem?
2t^2+t-3 = (2t+3)(t-1)
Therefore (2t+3)(t-1)(t+1) is a multiple of both polynomials. It is also the Least Common Multiple
(2t+3)(t-1)(t+1) can be written as
(2t+3)(t^2-1)= 2t^3 +3t^2 -2t -3
