Question

The number or variable for 5 is the number 4, and there’s a negative sign in between. For the parentheses in front of the 6 there is a negative sign. Could someone help me answer this problem ?

Answer 1

11x^4

Explanation:

The double negative automatically makes something positive. Your new expression is 5x^4 + 6x^4.

The only other thing you need to do is combine like terms by adding them together.

11x^4
