-2a^2
(2a + b)(a + 3b)
(a - 2b)(2a - b)
The expression 2a - 9a is a subtraction problem involving two terms with the variable 'a'. To solve this, you need to combine the coefficients of 'a'. In this case, 2a - 9a simplifies to -7a. This is because you are subtracting 9a from 2a, which results in -7a.
No
It is 2a-b simplified
(a - 6)(2a + 3)
The answer is 2a because of the two a's equal 2a
It is: 2a+5a = 7a when simplified
(2a+1)(a+1)
That factors to (2a - 7)(2a + 9)
