When the expression is broken down into its prime factors it is factored completely.
It is irreducible, it can't be factored.
That expression can not be factored.
It is irreducible, it can't be factored.
This quadratic expression can't be factored because its discriminant is less than zero.
When the expression is broken down into its prime factors it is factored completely.
If an expression does not have a common factor, then it is called a "prime" expression.

It is irreducible, it can't be factored.
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.
It's the general form of a quadratic expression and it can be factored providing its discriminant is not less than zero.
That expression can not be factored.
It is irreducible, it can't be factored.
This quadratic expression can't be factored because its discriminant is less than zero.
This quadratic expression can't be factored because its discriminant is less than zero.
If you mean (1+2x)2, that is already factored.
This expression can not be factored. It is already in it's simplest state.
