X2 Is an algebraic expression. X2 = 4 Is an equation that can be solved for X. The variable, X, in this case, has two values. In the expression any value can be substituted for X.
The value of the expression x2 + 9 will depend on what value you plug in for x. If you are looking to factor that expression, it can only be done using complex numbers:x2 + 9 = (x + 3i)(x - 3i)
4
x2 + 6x - 5 is a quadratic expression that can not be factored.
x2 - x - 6 is a polynomial expression, often referred to as a trinomial as it has three terms. If it were made equal to some value (for example x2 - x - 6 = 0) then it would become a quadratic equation. This particular expression can be factored :- x2 - x - 6 = (x - 3)(x + 2)

If you mean: x^2+15-3x then its value is 19 when x equals 4
The given expression does not have rational factors, so the question cannot be abut factorising. Evaluating x2 - 14x + 9 depends on the value of x.
You can't assign a value to this expression, until you know the value of "x".Assuming you mean x2 / (x+5), you can't simplify it either; there are no common factors. I would leave it just the way it is.You can't assign a value to this expression, until you know the value of "x".Assuming you mean x2 / (x+5), you can't simplify it either; there are no common factors.

It means that if you know the value of a variable, you replace every occurence of the variable with the value. For example, if x = 10, and you have the expression x2 + 5x - 3, you replace every x with 10, to get 102 + 5(10) - 3.It means that if you know the value of a variable, you replace every occurence of the variable with the value.

If you mean: x2+12x+35 then it is a quadratic expression that can be factored as: (x+5)(x+7)
x2 + 6x - 5 is a quadratic expression that can not be factored.
