expand the binomial, either binomial theorem, or just FOIL
bear in mind, we're assuming the coefficient "a" is 1
and we're also assuming is the first form, it could be the second, but we're assuming is a vertical parabola
D is the answer so u have to add and to make 7.5 a decimal u move it 2 places to the left
They ate the same amount of apple because 2 divided by 4 is .5, and so is 1 divided by 2. Have a nice night!
