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).

What is the difference of two square?
As for example: x^2-9 = (x-3)(x+3) when factored is the difference of two squares
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
