It is a quadratic expression

x^2 - y^2 - 4 is in its simplest form.

2m^2 - 8 -First you should factor out a two. --> 2(m^2-4) -You now have something squared minus something else squared; You have m squared minus 2 squared. Whenever you have something squared minus something squared as you do in this case, there is a simple rule to remember: You can reduce that expression into the quantity of the square root of the first number or variable plus the square root of the second number or variable Times the quantity of the square root of the first number or variable minus the second number or variable squared. --> In the case of your expression: ----> 2(m+2)(m-2)<-----

(x - 5)(x - 2)(x - 2)

(x - 2)(2x - 3)

It is a quadratic expression which can be factored to (7b+9)(8b-7) after dividing all terms by 2

No, it is not. To be correct, the expression requires parenthesis, which are missing.

negative 2 squared

Expression: x^2 -x -12 Completing the square: (x -0.5)^2 -12.25

They are terms of an expression because without an equality sign it is not an equation.

x³ - x² + x - 3 (x² + 1)(x - 1) - 2

This quadratic expression cannot be factored because its discriminant is less than zero

-32 - 2 - 5 = 2

The polynomial is not factorable with rational numbers. If you want to use irrational numbers it would be x minus the square root of 2 times x plus the square root of 2.

The answer is 4 squared minus 2 squared as 4 squared is 16 minus 2 squared, which is 4, gives you 12 as an answer.

None of them. It is -1.
