How do you find perfect square factors?
When an expression has the general form a²+2ab+b², then we can factor it as (a+b)². For example, x²+10x+25 can be factored as (x+5)². This method is based on the pattern (a+b)²=a²+2ab+b², which can be verified by expanding the parentheses in (a+b)(a+b).
Is 2 a factor of all perfect squares?
Therefore, the factors are 1, 2, 3, 4, 6, 9, 12, 18, and 36. Here, there is an odd number of factors because the square root of the perfect square (in this case 6) does not have a pair. Therefore, perfect squares have an odd number of factors because the square root of the perfect square does not have a pair.
What numbers have no perfect squares?
Please note that all the perfect square numbers end with 0, 1, 4, 5, 6 or 9 but all the numbers with end with 0, 1, 4, 5, 6 or 9 are not perfect square numbers. Example, 11, 21, 51, 79, 76 etc. are the numbers which are not perfect square numbers.
