= 4a2 + 2ab 2b2
It is 2a-b simplified
2b+b-4
7
a-b+a-b+2b+a = 4a
a+a+a+a+b+b - add the like terms =4a+2b 4a and 2b cannot be added because they are not like terms.
4a + 3c - 2b - c + a - b = 5a - 3b + 2c
7a-2b
To simplify the expression (3(a + b) + 2b(a + b)), we first factor out ((a + b)): [ = (a + b)(3 + 2b) ] This shows that the expression can be rewritten as the product of ((a + b)) and ((3 + 2b)).
10a - 10 b
2
It is: b+4 when simplified
2b
