It's an example of multiplying polynomials. In this case, they are polynomials of length 2, or binomials. Most people learn this as "FOIL", because that's easy to remember. For longer polynomials that you're multiplying, take one term from each grouped set of terms. Multiply these terms together. Repeat, being sure to choose a different combination of terms. Once you've done all possible choosings, add up all the terms you got from multiplying.

a million.) is authentic yet you may favor to combine the 20x and -6x time period into one time period: 14x 2.) is inaccurate, -a million * -x = x, you should have -2x^2+x+4x-2 and then combine your x words to: -2x^2+5x-2 3.) is inaccurate, 2x^2 * 4 = 8x^2, you should have 4x^3 + 8x^2 + -2x^2 + -4x, and after combing the x^2 words you've gotten 4x^3 + 6x^2 - 4x 4.) is authentic, besides the undeniable fact that, in case you blend like words, ab + -ba = 0 and your answer will be a^2 - b^2

This is clear example of the FOIL METHOD.
FOIL:
F = product of first terms
O = product of outer terms
I = product of inner terms
L = product of last terms
