Some expressions can't be factorised, and you have to use other methods to solve the equation.
Each number is called a factor. The answer is the product.
That is correct.
Factor it! Set each equal to zero! Solve
If they are multiples of 9, the digits add up to a multiple of 9.

For each of a list of algebraic expressions, find one or more common factors and factorise the expression.
In the equation 4 x 9 = 36, the product (36) is greater (larger) than each factor (4 and 9).

There are lots of different types of problems in algebra; you have to learn each type separately. For example, how to add similar expressions; how to multiply expressions; how to factor polynomials; how to solve equations; etc.

I think you are thinking of using the rectangles like you use Punnet squares. One side is multiplied times the other side and the product is put in the inside squares. This is handy when trying to factor expressions that are polynomials.
