If an expression does not have a common factor, then it is called a "prime" expression.
It's the general form of a quadratic expression and it can be factored providing its discriminant is not less than zero.
This expression can not be factored. It is already in it's simplest state.
6•2+6•3
It can be factored as 18(5-2x^2)
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.
It's the general form of a quadratic expression and it can be factored providing its discriminant is not less than zero.
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.
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.
x2+7x-18 = (x+9)(x-2) when factored
