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)
3a2b
(a^2 + 8b)(a^2 - 5b)
5
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
Expand 4ab3 (a2b2-a-1)
