12ab + 13b + 4 (assuming there's addition in the spaces)
b3 - 5b2 + 12 = (b - 2)(b2 - 3b - 6)Check:(b - 2)(b2 - 3b - 6)= b(b2 - 3b - 6) - 2(b2 - 3b - 6)= b3 - 3b2 - 6b - 2b2 + 6b + 12= b3 - 5b2 + 12
-6(a-3b-9c)
11a+7b-(3b-2a)
6+7a+6b
54qba
3A + 9B = 3(A + 3B)
It is: 4b+6
To simplify the expression (3b + 11c - 4b - c), first combine the like terms. For the terms with (b), subtract (4b) from (3b) to get (-b). For the terms with (c), subtract (c) from (11c) to get (10c). Thus, the simplified expression is (-b + 10c).
3b-4-6b-5
The expression "6b (3b)(6b 3b) 5" appears to be a multiplication of several terms. To simplify it, you would multiply the coefficients and combine the variables accordingly. However, without specific operations or parentheses indicating how to group the terms, it's unclear how to simplify it further. Please clarify the expression for a more accurate simplification.
To simplify the expression (8a + 4b + 4a + 3b), first combine like terms. Add the coefficients of (a): (8a + 4a = 12a). Then, add the coefficients of (b): (4b + 3b = 7b). Thus, the simplified expression is (12a + 7b).
