Expanding the expression:
(3b - 2)(3 - 2b) + 3b(2b - 3)= 3b(3) - 3b(2b) - 2(3) + 2(2b) + 3b(2b) - 3(3)= 9b - 6b^2 - 6 + 4b + 6b^2 - 9= 9b - 6b^2 - 6 + 4b + 6b^2 - 9= 13b - 15
Therefore, the expression simplifies to 13b - 15.
Expanding the expression:
(3b - 2)(3 - 2b) + 3b(2b - 3)
= 3b(3) - 3b(2b) - 2(3) + 2(2b) + 3b(2b) - 3(3)
= 9b - 6b^2 - 6 + 4b + 6b^2 - 9
= 9b - 6b^2 - 6 + 4b + 6b^2 - 9
= 13b - 15
Therefore, the expression simplifies to 13b - 15.
