Why can't 7x 5 be factored?
I will assume you mean 7x + 5. In general, a binomial (two terms) can ONLY be factored if both terms have a common factor, OR you have a difference of squares. No other cases are possible, since the product of two binomials is, in general, a trinomial (three terms). Since none of these special cases apply, the expression can't be factored.
How do you combine unlike terms?
Unlike terms are terms in an equation that are different. These terms cannot be combined. Like terms, however, can be combined.
What is completely factored form?
A completely factored form is one which is composed of product of factors and can't be factorized further. Let us consider two examples: x2 - 4x + 4 is not a factored form because it can be factored as (x - 2)(x - 2). (x +1)(x2 - 4x + 4) is also not a factored form because x2 - 4x + 4 can be factored further as (x - 2)(x - 2). So, the completely factored form is (x + 1)(x - 2)(x - 2).
What is 2x plus 1x plus 9?
They are terms of an algebraic expression that can be simplified to: 3x+9 or factored to 3(x+3)
What property is 3x plus 12 plus x?
They are terms of an expression which can be simplified to 4x+12 or factored to 4*(x+3)
