Best ResponseYou've already chosen the best response.0When you subtract polynomials you should change the "" sign that is in between the two polynomials to a "+" and then change the sign of every term in the second set of parentheses. ex. (3x^2 + 11x + x^4) + (x^2  14x + 9x^4)

Best ResponseYou've already chosen the best response.0Then you add like terms... you should always put the highest powered x first down to the lowest powered x.. so in this case You should add x^4 _ 9x^4 first and get 10x^4. Then add the x^2s so you get 3x^2  x^2 = 4x^2 Then add the xs so you get 11x  14x = 3x So your answer is 10x^4  4x^2  3x Do you understand?
