-4 is a negative number and is less then zero, 4 is a positive number and is more then zero.

A square number is just a number that you get when you square a lower number so there are a few examples here. 4 (4 is 2 squared and is even) 16 (16 is 4 squared and is even) 36 (36 is 6 squared and is even) Any even number squared should give another even number therefore the list is endless.

It is the difference of squares. (x-4) and (x+4) <--- answer

If the square root of a natural number is not an integer, then it is irrational. Another way to look at it: if a natural number N falls between two perfect squares, then the square root of N is irrational.So in this case, 12 is between 9 (3 squared) and 16 (4 squared). So the square root of 12 is between 3 and 4, and also the square root of 12 is irrational.

Either 2i or -2i, when squared equal -4.

When a number is squared, it has been multiplied by itself. For instance: 4 squared means 4x4, which is equal to 16.

Because in parenthesis you have to multiply it by something.

33 = 3x3x3 = 9 22 = 2x2 = 4 The difference between them is 5 (9-4).

seven 4 x 4 = 16 3 x 3 = 9 16 - 9 = 7

3 squared is 9 and 4 squared is 16, so the square root of any whole number between 9 and 16 will be irrational.

The prime number between 4 and 7 is 5. So 5 squared is 25.

(2x2+4xy-3)-(x2-2xy-4)Answer: x2+6x+1

A squared number is the product of an integer times itself. So, 16 is a squared number. 4 * 4 = 16.

The difference is that they are both totally different things. When you times something by two you're just doubling it and when you square something you times it by itself. Ex: 1x2=2 2x2=4 3x2=6 These are all doubling. Ex:1 squared is the same as 1x1 2 squared is the same as 2x2 3 squared is the same as 3x3 These are all numbers squared

2 centimeters is just 2 centimeters, and 2 centimeters squared is 4 centimeters. 2 centimeters x 2 centimeters = 4 centimeters squared = times 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.
