    factor problem

    This is the problem:
    Factor: 14(x-y) + (x-y)squared + 49

    If the first and second terms were switched, I could figure it out on my own, but, alas, they are not. It was written in the book this way. Could someone explain how to solve this? Thank-you.

    Hello,

    Let (x-y) be X

    So you have X^2+2*7*X+7^2

    you can switch the first and the second term, as the addition is commutative oO

    I knew that addition is communative, but I didn't know you could do that for this problem. It's too simple, lol. Thank-you.
