2ab = 2*(-2)*7 = -28
(a2+2b2-2ab)(a2+2b2+2ab)
It is an expression
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!
n(2a - b)(2a + b)(4a^2 - 2ab + b^2)(4a^2 + 2ab + b^2)
-2ab
2ab-2 = 0
2ab-6bc = -4
2ab = 2*(-2)*7 = -28
ab(ab) =2ab
a^2 + b^2 + 2ab = (a + b)^2
The GCF is 2ab.
(a2+2b2-2ab)(a2+2b2+2ab)
2ab - 3b2 - 3b + 2a does not have a solution, as it is not an equation.

well here is the quadratic equation: -b plus or minus the square root of b2 - 4ac over 2a. (I don't know how to format it in typing) here's one: A2 + 2AB + B2 = (A+B)2
