Remember how I said grouping like terms is equivalent to adding or subtracting polynomials? Well, this still holds true when subtracting polynomials!
TO SUBTRACT POLYNOMIALS! > ADD THE OPPOSITE
That is, we change this subtraction problem into an addition problem by "ADDING THE OPPOSITE." This means the terms in any polynomial that follow the subtraction sign are changed to their opposite (positive to negative, negative to positive).
