${x}^{2} + 5 = 7 \\ {x}^{2} = 7 - 5 \\ {x}^{2} = 2 \\ \\( {x}^{2} + 5)k = 21 \\ (2 + 5)k = 21 \\ (7)k = 21 \\ 7k = 21 \\ \frac{7k}{7} = \frac{21}{7} \\ k = 3$

Describe how you can find the prime factorization of a number

gogolik [260]

I think it would be easier to understand when u see a problem worked out, prime factorization of 18:
18
/\
6X3
/\
3X2
so the prime factorization is 2X3X3
hope that was helpful! :D
