Who can factor 64a6n - b6n?
n(2a - b)(2a + b)(4a^2 - 2ab + b^2)(4a^2 + 2ab + b^2)
What is -a x 2 x b-3?
5
What is A B squared?
A^2-2ab+B^2 is actually (A+B)^2 AB squared is A^2B^2 or (AB)^2
What is formula for a minus b whole square?
(a-b)2 = a2 _ 2ab+b2
Is a squared plus b squared the same as a plus b squared?
No. If you expand (a + b)2 you get a2 + 2ab + b2. This is not equal to a2 + b2
what is 2ab if a=7 and b=2?
504
What is a square b square 2ab?
a^2 + b^2 + 2ab = (a + b)^2
How do the squares of sums and differences relate?
(a + b) = a^2 + 2ab + b^2 (a - b)^2 = a^2 - 2ab + b^2 or you can work like this: [a + (-b)]^2 = a^2 + 2a(-b) + (-b)^2 (a - b)^2 = a^2 - 2ab + b^2
Show a plus b divided 2 equals 2ab divided by a plus b?
b/2=2ab/+b means112.5
Who can factor 64a6n - b6n?
n(2a - b)(2a + b)(4a^2 - 2ab + b^2)(4a^2 + 2ab + b^2)
Who can factor 64a raised to 6n - b raised to 6n?
n(2a - b)(2a + b)(4a^2 - 2ab + b^2)(4a^2 + 2ab + b^2)
What is A(2)?
It is a trinomial.The square of (a + b)^2 is a^2 + 2ab + b^2.
What is squre of binomial?
It is a trinomial.The square of (a + b)^2 is a^2 + 2ab + b^2.
What is 2a times b?
2ab
How do you compare half of a add b and a add b dividing 2ab?
Algebraically:((a+b) / 2) / ((a+b) / (2ab)) = 2ab(a + b) / 2(a + b) = (2a2b + 2ab2) / (2a + 2b) = abAs an example, let a = 2 and b = 3 then:i) (a + b) / 2 = (2 + 3) / 2 = 5/2ii) (a + b) / (2 * a * b) = (2 + 3) / (2 * 2 * 3) = 5 / 12Therefore i) is ab times larger than ii). (for these specific example numbers it will be 6 times larger)
What is -a x 2 x b-3?
5
What is A B squared?
A^2-2ab+B^2 is actually (A+B)^2 AB squared is A^2B^2 or (AB)^2
