Answer:
-8205 - 9x² -11x - 2x³
Step-by-step explanation:
Lets take the unknown number to be subtracted as 'y'.
(623 - 9x² + 15x - 3) - y = (2x³ + 94² + 26x - 12)
623 - 9x² + 15x - 3 -y = 2x³ + 94² + 26x - 12
623 - 9x² + 15x -3 - (2x³ +94² + 26x - 12) = y
623 - 9x² + 15x - 3 - 2x³ - 94² - 26x + 12 = y
623 - 94² + 12 - 3 - 9x² + 15x - 26x -2x³ = y
623 - 8836 + 8 - 9x² - 11x - 2x³ = y
-8205 - 9x² -11x - 2x³ = y
