Answer: The letters and numbers you will plug in in order are 8, Q, O (upper case o not zero), b, 6, o (lower case o not zero), b, D, M

Explanation:

This is what I would write down for show work line by line. (Also this (6x^2) is six x squared.)

-2x

((-2x)^2) - (-2x) + 1

(4x^2) + 2x + 1

3((4x^2) + 2x + 1) + 1

(12x^2) + 6x + 4

(((12x^2) + 6x + 4)^2) - ((12x^2) + 6x + 4) + 1

(144x^4) + (144x^3) + (132x^2) + 48x + 16 - ((12x^2) + 6x + 4) +1

(144x^4) + (144x^3) + (120x^2) + 42x + 13

3((144x^4) + (144x^3) + (120x^2) + 42x + 13) + 1

(432x^4) + (432x^3) + (360x^2) + 126x + 40

-2((432x^4) + (432x^3) + (360x^2) + 126x + 40)

(-864x^4) + (-864x^3) + (-720x^2) + (-252x) + (-80)

-2((-864x^4) + (-864x^3) + (-720x^2) + (-252x) + (-80))

(1728x^4) + (1728x^3) + (1440x^2) + 504x + 160

3((1728x^4) + (1728x^3) + (1440x^2) + 504x + 160) + 1

(5184x^4) + (5184x^3) + (4320x^2) + 1512x + 481

(((5184x^4) + (5184x^3) + (4320x^2) + 1512x + 481)^2) - ((5184x^4) + (5184x^3) + (4320x^2) + 1512x + 481) + 1

(26873856x^8) + (26873856x^7) + (22394880x^6) + (7838208x^5) + (2493504x^4) + (26873856x^7) + (26873856x^6) + (22394880x^5) + (7838208x^4) + (2493504x^3) + (22394880x^6) + (22394880x^5) + (18662400x^4) + (6531840x^3) + (2077920x^2) + (7838208x^5) + (7838208x^4) + (6531840x^3) + (2286144x^2) + 727272x + (2493504x^4) + (2493504x^3) + (2077920x^2) + 727272x + 230880 - ( (5184x^4) + (5184x^3) + (4320x^2) + 1512x + 481) + 1

(26873856x^8) + (53747712x^7) + (71663616x^6) + (60497280x^5) + (39320640x^4) + (18045504x^3) + (6437664x^2) + 1453032x + 230880

(8x^8) + (Qx^7) + (Ox^6) + (bx^5) + (ox^3) + (bx^2) + Dx + M
