Yes.
The GCF is 7a.
Since 7a is a factor of 14ab, it is automatically the GCF.
7a 7a * 4 = 28a 7a * 7b = 49ab
Yes.
To factorize the expression 7a^2 - 8ab, you need to find the greatest common factor of the two terms. In this case, the common factor is a. So, you can factor out an 'a' to get a(7a - 8b) as the factored form of the expression. This means that 7a^2 - 8ab can be simplified as a multiplied by the quantity (7a - 8b).
7a2
(5a + 2)(a + 1)
7a
(7a - 1)(6a + 1)
Use a factor tree. 98 49,2 7,7,2
Since 49 is a factor of 98, it is automatically the GCF.
