6a squared-8ab+2a factor completely and check mentally
12a2b + 6a = 6a(2ab + 1)
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)
6a
6a + 6b = 6(a + b)
6a^b-18ab^2+24ab
6a squared-8ab+2a factor completely and check mentally
(7a - 1)(6a + 1)
12a2b + 6a = 6a(2ab + 1)
(2a - 3)(3a - 4)
6ax2 + 6ax + 6a = 6a(x2 + x + 1)
6a to the second power minus 8ab + 2a
(a + 9)(a - 3)
36a2 - 60a + 25 = 36a2 - 30a - 30a + 25 = 6a(6a - 5) - 5(6a - 5) = (6a - 5)(6a - 5) = (6a - 5)2
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)
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)
a+6a+a=8a
