Jessica is baking a cake. The recipe says that she has to mix 96 grams of sugar into the flour. Jessica knows that 1 cup of this
particular sugar has a mass of 128 grams. She added one over two of a cup of sugar to the flour. Should Jessica add more sugar to make the exact recipe, or did she go over and by what amount?
first make the coefficient of x alone... So that you should take the 4 out... then you get 4times x squared + 5x then you should didvide the x term by 2(always) and then you get 5/2...So then the third term or the constant is tye square of that..
