The difference of two squares is quick way to factor polynomials when certain constraints are met: Namely that you have two squares (e.g. 4, 25, 36x2 , 144a6) and one is subtracting from the others (e.g. 25 - 36x2).
IF these two constraints are met, then you are able to factor the polynomial by finding the square roots of the squares.
sqrt(25)=5
sqrt(36x2) = 6x
Therefore 25 - 36x2 = (5+6x)(5-6x) in factored form.
In general, given any two squares, a2 and b2, AND they are subtracting, a2 - b2, you can factor them to be (a + b)(a - b).

In a square and in a rhombus opposite sides are parallel to each other and all sides are equal. What is the difference between the two figures?
A square has four right angles, a rhombus doesn't.
What is the shape that has four sides the same length?
I don't know if there's a specific name for these two shapes, but the only two shapes that have 4 equal sides are the square and rhombus. The difference between the two is the square has 4 equal angles (90 degrees) and a rhombus does not.
What is the similarity and difference between a square and rhombus?
A square is well a square while a rhombus is a square on one of the corners (a square diamond)
What is the approximate difference in tenths between the square root of 10 and the square root of 15?
The approx difference is 0.7
What is different about a perfect square and a difference of two squares?
"Perfect square" means that you square a whole number. Sometimes simply called "square" or "square number". "Difference of two squares" is the result of subtracting one such square from another. In most cases, the difference will not itself be a square.
What is the difference between Two meter square or two square meter?
A two metre square is a square with sides of two metres. This would have an area of 4 square metres. 2 square metres is the area of square with sides sqrt(2).
What is the difference of the square of two primes is 40 What are these two primes?

The difference of two irrational numbers is an irrattinal number?
The sum, or difference, of two irrational numbers can be rational, or irrational. For example, if A = square root of 2 and B = square root of 3, both the sum and difference are irrational. If A = (1 + square root of 2), and B = square root of 2, then, while both are irrational, the difference (equal to 1) is rational.
