Solve
(3a+1*3a+1*3a+1)-(2a-1*2a-1*2a - 1)
Simplifying,
(3a+3a+3a+1)-(2a-2a-2a-1)
= (9a+1)-(-2a-1)
= 9a+1+2a+1
= 11a+2
(Yahoo Answers has an interesting away of eating up repeated patterns, vary the pattern will prevent this, like putting in some spaces).

Nagpapatawa ba kayo?
If you're asking about simplifying (3a + 1)^3 - (2a -1)^3, then answer is 19a^3 + 39a^2 + 3a + 2

(3a+1*3a+1*3a+1)-(2a-2a-2a-1)
3a+3a+3a+1-2a+2a+2a+1
13a+2-2a
11a+2
