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

What is A(2)?

It is a trinomial.The square of (a + b)^2 is a^2 + 2ab + b^2.


Is ab squared the same as 2ab?

No, ab squared is not the same as 2ab. ab squared (ab^2) means multiplying ab by itself, resulting in a^2 * b^2. On the other hand, 2ab means multiplying 2 by a and then by b, resulting in 2ab. These two expressions are not equivalent because ab^2 involves squaring the variable b, while 2ab does not involve squaring any variables.


Is a perfect square trinomial of the form a2-2ab b2 16x2-36x 9 true or false?

False. A perfect square trinomial takes the form ( (a - b)^2 = a^2 - 2ab + b^2 ) or ( (a + b)^2 = a^2 + 2ab + b^2 ). The expression ( 16x^2 - 36x + 9 ) can be factored as ( (4x - 3)^2 ), which confirms it is a perfect square trinomial, but it does not fit the specified form ( a^2 - 2ab b^2 ).


What is squre of binomial?

How will you differentiate the square of sum from the square of a difference?

The square of a sum, expressed as ((a + b)^2), expands to (a^2 + 2ab + b^2). In contrast, the square of a difference, represented as ((a - b)^2), expands to (a^2 - 2ab + b^2). The key difference lies in the sign of the middle term: the square of the sum includes a positive (2ab), while the square of the difference includes a negative (2ab). This distinction affects the overall value of the expressions when (a) and (b) are not equal.
