To find the sum of these two expressions, you first need to simplify each expression separately and then add them together.
Expression 1: x-4^2+6
= x - 16 + 6
= x - 10
Expression 2: -(2x^2 + 8 - 3x)
= -2x^2 - 8 + 3x
= -2x^2 + 3x - 8
To know whether the sum would be adding or subtracting, you need to look at the sign between the two expressions. In this case, the sign between the two expressions is a positive sign, which means that you need to add the two simplified expressions together.
Therefore, the sum of x-4^2+6 and -(2x^2+8-3x) is (x-10) + (-2x^2 + 3x - 8) = -2x^2 + 4x - 18.
