well what you do is the following:
a=6 right so 3x6=18 you times 6 by 3 because its 3a.
so than you do 2 x 4 because b is the value of 4. =8
18-8=10 10 is your answer
3a2b(2b2-1)
Either b4 + b5 +b6 or sum(b4:b6)
If you copy the content of cell B4 to cell C6, the resulting cell reference in C6 will be adjusted based on the relative position of the cells. Since C6 is two columns to the right of B4 and in the same row, C6 will reference the value in B4 directly as it is a relative reference. Therefore, C6 will display whatever value or formula was originally in B4.
(a^2 + 8b)(a^2 - 5b)
3a2b

1. d2. c3. b4. a5. a6. b7. a8. c9. b10. D11. A12. D13. c14. c15. D16. C17. D18. B19. B20. d
a3+b3=(a+b)3-3a2b-3ab2
(a + b)3 = a3 + 3a2b + 3ab2 + b3
The formula I am using is: =ROUND(IF(A6="","",IF(VLOOKUP(A6,'Pricing File '!A:N,12,FALSE)=0,(VLOOKUP(A6,'Pricing File '!A:J,8,FALSE)),(VLOOKUP(A6,'Pricing File '!A:N,12,FALSE)))),6)
b4
(a + b)3 = a3 + 3a2b + 3ab2 + b3
