I expect the second term is NOT 6x15in which case, there is an arithmetic symbol missing between 6x and 15.
x2+ 6x + 9 is the completed square so you will need to work out what needs to be added: depending on -15 or +15.

What number must you add to complete the square of x2 12x -9?
The idea is to take half the linear part (12, in this case), then square it. The constant part must be equal to this result.

square root -5 minus 14 or - square root -5 minus 14
How can you tell by looking at the prime factors of 17640 that the square root of 17640 is not a whole number?
Write the prime factors as powers. In a square number, each prime number appears an even number of times - i.e., an even power. Examples: 4 = 22 (even power, this is a square) 144 = 24 x 32 (all powers are even, this is a square) 12 = 22 x 3 or 22 x 31 (3 has an odd power so it is not a square) (If a number is a perfect square, that is equivalent to saying that its square root is a whole number.) * * * * * In this case there is a particularly fast method. The number ends in 0 so 10 must be a factor of the number. That is to say, 2 and 5 must be prime factors of the number. If it is a square then 22 and 52 must be factors of the number ie 22 x 52 = 100 must be a factor. But if 100 is a factor, the number must end in 00. It does not so it cannot be a square.
