The given terms can be simplified to: a -b
(a+b)(3b+1)
3b
If a + b = 6, what is the value of 3a + 3b?
2A plus 3B times 2A - 3B = 4A2 - 9B2; this is an example of the general formula (a + b)(a - b) = a2 - b2.
(2a + b)(a + 3b)
6
This expression can be factored. ab + 3a + b2 + 3b = a(b + 3) + b(b + 3) = (a + b)(b + 3)
-3b=96+b -4b=96 b=-24
3a+ax+3b+bx = 3(a+b)+(a+b)x = (a+b)(3+x)
It is: b+b+b = 3b
If you mean 3b+9 = 12 then b equals 1
