(2a+1)(a+1)
2a+7 is a binomial, because it has two terms (2a and 7).
(a - 2b)(2a - b)
No
That factors to (2a - 7)(2a + 9)
You would factor out -1 (a) from a trinomial in an equation such as -a^2 +30a - 2a + 60 after the middle term has been separated. The final answer of this trinomial would then be (a-30) (a-30).
(2a+1)(a+1)
6a squared-8ab+2a factor completely and check mentally
I guess you mean: 2a^2+6a Well in this case you take 2a out of the bracket and then you're left with a+3 inside. 2a(a+3a)
(2a - 3)(3a - 4)
2a+7 is a binomial, because it has two terms (2a and 7).
6a2 - 8ab + 2aas you can see a is common to all terms. And 2 is a factor of 6,8, and 2. So 2a is a factor of all three terms:2a(3a-4b+1)
(2a + b)(a + 3b)
(a - 2b)(2a - b)
4aa-bb fits the special type of polynomial in the form of x**2-y**2 which can be rewritten as (x-y)(x+y) sqrt(4aa) = 2a sqrt(bb) = b (2a-b)(2a+b)
No
(2a + 1)(2a - 5)
