No
(a - 2b)(2a - b)
(2a+1)(a+1)
That factors to (2a - 7)(2a + 9)
The verbal expression of 3b to the second power plus 2a to the 3rd power is "three b squared plus two a cubed."
(2a + b)(a + 3b)
No
(a - 2b)(2a - b)
(2a+1)(a+1)
That factors to (2a - 7)(2a + 9)
(a2 + a + a2) = (2a2 + a) = a (2a + 1)
6a squared-8ab+2a factor completely and check mentally
(2a - 3)(3a - 4)
The verbal expression of 3b to the second power plus 2a to the 3rd power is "three b squared plus two a cubed."
There are no like terms here.
If your Problem is organized like this: A x squared plus B x plus C, the equation is: (B plus or minus the square root of(B squared minus 4 A C)) over 2A
a + a + a - 2a = 3a - 2a = a
