(-a-7b+5)4ab
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
(4ab^2 + 3cd)(4ab^2 - 3cd)
a^2b^2(4ab) = 8a^3b^3.
2a(2b) Would Give You The Answer 4ab. 2x2 = 4 And a x b = ab.
(-a-7b+5)4ab
5a³ - 4ab + 2a³ = (5+2)a³ - 4ab = 7a³ - 4ab.
4a2 + 4ab - y2 + b2 You cannot simplify this expression because it does not contain like terms, but you can factor it such as: 4a2 + 4ab - y2 + b2 = (4a2 + 4ab + b2) - y2 = (2a + b)2 - y2 = [(2a + b) - y][(2a + b) + y]
(4ab^2 + 3cd)(4ab^2 - 3cd)
4a2+4ab+b2 in2
4ab
4ab
The greatest common factor of 4ab and 6ab is 2ab. You simply take the greatest common factor from both factors. The greatest common factor of 4 and 6 is 2. The letters can be factored out because they appear in both factors
Well, isn't that just a happy little math problem we have here? To factorise 4ab - 6ab, we can first factor out the common factor, which is 2ab. So, we have 2ab(2 - 3) or simply 2ab(-1). And just like that, you've simplified the expression beautifully!
2a*2b = 4ab
4ab - 2a - 7
Urmm 4ab ?
