Squares have four equal sides and equal angles, rectangles only have two.
a2 - b2 = (a + b)(a - b).
Squares of prime numbers, among others.
It is the difference of two squares which is: (6-10w)(6+10w)
a^2 - b^2 = (a - b)(a + b) a^2 + b^2 doesn't factor rationally.
There is a formula for the difference of two squares. The sum of two squares doesn't factor.
Squares have four equal sides and equal angles, rectangles only have two.
The formula to factor the difference of two squares, a2 - b2, is (a + b)(a - b).
Prime squares
a2-b2=(a-b)(a+b)
x^2 - 64.
Can I call you justin, que
a2 - b2 = (a + b)(a - b).

The difference of two squares: 4 -9 = (2-3)(2+3)
x2 + 36 cannot be factored. You can only factor the difference of two squares, not the sum.
The "difference of squares" has a formula. (11x + 1)(11x - 1)
