((x+2)(x+2))-((x-5)(1))=A
x^2+4x+4-x+5=A
x^2+3x+9=A
So it's 2.40 subtract 2, which is 0.4
then put it over 2, you get 0.4/2, which is equal to 0.2
0.2= 20% so it's 20% of increase
Just add the numbers in without the dollar sign in front. Have one axis as money and the other as amount then add in the data.
5x^2+45x-7x+63
5x^2+38x+63
