-2a plus 3b

4a + 3c - 2b - c + a - b = 5a - 3b + 2c

It is an algabraic expession without knowing whether or not 2b and 3a are plus or minus

8a+2b

Gathering like terms together, this is equal to 5a + 3b + 7c.

5a(2b + 1)

(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].

-6(a-3b-9c)

6+7a+6b

The given expression can be simplified to: 3b-a

6a+7b

no

This is not a difficult factorisation, as it is merely a normal factorisation with "a" stuck on the end of each number. 25a(2) - 20ab + 4b(2) (2b-5a)(2b-5a) This is: 2bx2b=4b(2) 2bx-5a=-10ab (twice) -5ax-5a=25a

11a+11b

It is not an equation but an algebraic expression that can be simplified to: 12b-5a

12a + 6b + 6c = 6(2a + b + c)

5a(a+2b+b²)

No

6b+5a-4b+3a= ? Rearrange it as 5a+3a+6b-4b = 8a+2b

5a

2a-5

2a + 3b

6a+7b. This cannot be simplified anymore unless you know a or b.

2a+5
