6a squared-8ab+2a factor completely and check mentally
Divide by 6a: 6a(a + 3b)
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
2a*3 = 8+4a 6a = 8+4a 6a-4a = 8 2a = 8 a = 4
= 2a - 10
6a squared-8ab+2a factor completely and check mentally
(2a - 3)(3a - 4)
6a to the second power minus 8ab + 2a
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)
Divide by 6a: 6a(a + 3b)
Since the question is 3(2a), then just write it out. 3(2a) is 2a+2a+2a or 6a.
2a-6a+9-4a+9
If you mean -2a+6a then it simplifies to 4a
The GCF of 6a^2 and 8a is 2a.
(a - 6)(2a + 3)
(2a+1)(a+1)
6a
