6ab2 + 7a2b
find the common variables and numbers:
In this case only the variables are common and they are a & b. so you take out a &b out of the brackets and factorise.
Answer: ab(6b+7a)
It is: 5(3a+b) when factored
2a2b2+3a2b2-5abc
To evaluate it you need to know both b and a. But it is possible to factorise it as follows: b2-a2 = (b-a)*(b+a)

For a polynomial a2 - b2 = (a + b)(a - b).So for x2 - 16y2 ---> a = x, and b = 4y: (x + 4y)(x - 4y)
It is: 5(3a+b) when factored
The factors of 6Ab^2 are the numbers or variables that can be multiplied together to result in 6Ab^2. In this case, the factors of 6Ab^2 are 1, 2, 3, 6, A, B, A^2, B^2, AB, 2A, 3A, 6A, 2B, and 3B. These factors can be combined in various ways to represent the original expression 6Ab^2.

-9(a + b)
To evaluate it you need to know both b and a. But it is possible to factorise it as follows: b2-a2 = (b-a)*(b+a)
It is possible to factorise 4x²-9 further.Factorising is to express a number or expression as a product of factors.The technique of factorising two terms: a² - b² = (a + b) (a - b)If we apply ( 4x²-9 ) to the previous technique: 4x² - 9 = (2x + 3) (2x - 3)

2a + 4b + 8c = 2(a + 2b + 4c) You could also continue by factoring the inside of the parentheses a bit: 2a + 4b + 8c = 2(a + 2b + 4c) = 2(a + 2[b + 2c])
