Expand ( 2 + x + x^2 )^5 up to the term in x^3 and evaluate (2.205)^5 to 4 dp

Which describes the difference between the graph of f(x)=x^2 and g(x)=-(x^2-2)

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
