8a-4b-3a+6b=5a+2b

No, just use distributive property.
FOIL is when you have something like (x-a)(x+c).
Just take the 4 and multiply it by the (2a-b). Then take the 3 and multiply it by the (a-2b). Then combine like terms.
4(2a-b) - 3(a-2b) =
8a - 4b - 3a +6b =
5a + 2b
Hope that helps! :-)

Not exactly. The FOIL method is used to multiply two polynomials. The second polynomial is being subtracted from the first.
4(2a-b)-3(a-2b)
(8a-4b)-(3a-6b)
(8a-3a)+(-4b+6b)
5a+2b

This problem is a distributive problem so you would multiply 2a-b times 4 and then multiply a-2b times -3. Once you have those terms multiplied out add your like terms.
FOIL works when you are multiplying a binomial times a binomial, such as (x-3)(2x+5).
Hope this helps. Good Luck.

No.
4(2a-b) -3(a-2b)
8a-4b-3a+6b
5a+2b

FOIL is used for multiplying. Here's the answer, not using FOIL:
4(2a-b)-3(a-2b)
(8a-4b)-(3a-6b)
8a-4b-3a+6b
5a+2b

No, the foil method is for this kind of question (a+b)(c+d)
First, you multiply, then gather like terms and simplify.
8a-4b-3a+6b= 5a+2b! Hope this helps.

You use "FOIL" when you are multiplying the sum of two things and the sum of two things. That is not this. Here, you distribute the 4 and the -3 (not 3 itself), and add.

No you distribut the 4 and the 3 and then you solve the like terms.
