To factorise the expression (4a + 12b), first identify the greatest common factor (GCF) of the coefficients. The GCF of 4 and 12 is 4. You can then factor out 4 from the expression:
[ 4(a + 3b). ]
Thus, the factorised form is (4(a + 3b)).
The LCM is 36bc^3.
24 = 48 - 12b subtract 48 from each side -24 = -12b divide both sides by -12 2 = b
4a*4a*4a = 64a3 cubic units

a²-a = a(a-1)
6a -12b + 30 = 6 (a - 2b + 5)
2 x (2a + 3b - 6)
12b-4
The LCM is 36bc^3.
(4a)2 or 16a2
24 = 48 - 12b subtract 48 from each side -24 = -12b divide both sides by -12 2 = b
4a*4a*4a = 64a3 cubic units
36ab = 3a x 12b so is the LCM
Well my 13 year old daughter is a 12B!
What is the additive inverse of -4a?
8
a²-a = a(a-1)
