The answer would actually be A F(x)=3x^2+4x G(x)=2x^2-x+1 The two x^2 items are both positive and are added together to be 5x^2 The two x items would be added together to get 3x cause of the -x Then +1 is just +1 Making the equation 5x^2+3x+1 If we were subtracting you would be absolutely correct, but since we are adding would go the opposite direction. I hope this helps!
