Squaring a binomial can be done by writing the binomial twice and multiply using FOIL method.EX: (x+3)2 = (x+3)(x+3) = x2 +3x +3x +9 = x2 + 6x +9
It can be factored as the SQUARE OF A BINOMIAL
You multiply each term of one binomial by each term of the other binomial. In fact, this works for multiplying any polynomials: multiply each term of one polynomial by each term of the other one. Then add all the terms together.
It is not possible for a perfect square to have just 2 terms.
A quartic.
To calculate the cube of a binomial, you can multiply the binomial with itself first (to get the square), then multiply the square with the original binomial (to get the cube). Since cubing a binomial is quite common, you can also use the formula: (a+b)3 = a3 + 3a2b + 3ab2 + b3 ... replacing "a" and "b" by the parts of your binomial, and doing the calculations (raising to the third power, for example).
The binomial usually has an x2 term and an x term, so we complete the square by adding a constant term. If the coefficient of x2 is not 1, we divide the binomial by that coefficient first (we can multiply the trinomial by it later). Then we divide the coefficient of x by 2 and square that. That is the constant that we need to add to get the perfect square trinomial. Then just multiply that trinomial by the original coefficient of x2.

You have to multiply each term in the first binomial, by each term in the second binomial, and add the results. The final result is usually a trinomial.

For binomial expansions. (When you have to multiply out many brackets, binomial expansion speeds things up greatly).
if the bar between the x's means multiply... x2 is a binomial because if you have an x squared this indicates that... x2 + 0x + 0 which is a binomial expression

Yes, the chi-square test can be used to test how well a binomial fits, provided the observations are independent of one another and all from the same (or identical) binomial distribution.
