(x+9)^2 =x^2 + 9
X^2 + 18x + 81 = X^2 +9
18X + 72 = 0
18X = -72
X =- 4
Prime numbers have two factors. All square numbers (other than 1) have more than that.
No, because 1 times itself is one, making it not a square number. It has to equal a different number than the number times itself. * * * * * A totally incorrect answer - on two counts. (a) a square number does not have to be different and, (b) even if that were the case, 1 is the square of -1 and -1 is not the same as 1.
#2. since 1 is a square number. and a prime number is positive with only two positive natural number divisors: 1 and itself.
You can square any number.

The square of 9 more than a number is equal to nine more than the square of a number. What is the number?
-4
-4
-4
No. Since the square root of a number is whatever number times itself will equal the given number, there can be only one.
No, not always since: if a number is more than 1, then its square root is smaller than the number. if a number is less than 1, then its square root is bigger than the number.
There are an infinite number of points on two adjacent sides of a square which can be joined to the diagonally opposite point, so there is an infinite number of ways of halving a square.

4,6,8,10ok, that's kool, now what the hell is the answer to this mind blower?!?!The square of 9 more than a number is equal to 9 more than the square of the number What is the number? the answer is 10,8,6 and 4
The same for both. Both a square and a rectangle have 4 equal angles.
No, square numbers (other than 1) have more than two factors.
It is if the number is more than ' 1 '. If the number is less than ' 1 ', then it's smaller than its own square root.
