In order to multiply these polynomials together, you will take both terms of the first polynomial and multiply them by each term in the second polynomial. You can then combine any like terms to get your final answer.
Well, I would simplify the expression because you don't know x. Combine all your like terms first 2x^2-4x^2-5x-12x+10 Then add the like terms together 6x^2-(-7x)+10 That would be your final answer! I don't know if it is correct or not, depending the other answers you get. You can also google it if it doesn't help♀️
