12b3
4(16a4 + b2)
(2b - 1)(2b + 1)
4b2-16 =4(b2-4) =4(b+2)(b-2)
ok i need help with this someone help
4(4a2 - b2) 4(2a + b)(2a - b)
8/12 = 4/3b8/12 = 4 x b/33x8/12 = 4xb24/12 = 4b2 = 4b2/4 = 4b/4b = 2/4b = 1/2
C. 12b3
Not sure about the greatest commom factor, but the greatest common factor is b.
Proper factors do not include one and the number itself. The only one left is 2.
Area = ½base x height = 18; h = 4b, so b/2 x 4b = 18 ie 4b2 = 36making b2 = 9 and b = 3 inches
Assuming the missing sign is "minus" then you have the difference between two squares. This is solved as (x + y)(x - y). In your example x = 4a and y = 2b so the factorisation is (4a + 2b)(4a - 2b) or more completely: (4)(2a + b)(2a - b).
