Some special cases that are relevant in practice are: (a + b)2 = a2 + 2ab + b2 (a - b)2 = a2 - 2ab + b2 (x + a)(x + b) = x2 + (a+b)x + ab
This can't be explained in a few words. Basically you check the different special cases, mentioned in a school algebra course: whether there is a common factor, whether a binomial is a difference of squares, etc. Check a high school algebra book for more details.
Not if the rational number is zero. In all other cases, the product is irrational.
Parallelograms (and their special cases), isosceles trapezium.
A hexahedron. In special cases it would be a cuboid and, in even more specific cases, a cube.
