Math problem - polynominals

[liv]

My daughter asked me. I could not help her. And I used to be good that this. Old age. What can I say. (it is about factoring)

(a-5)squared -36

Yup I am stumpted.

You have

a^2 - b^2 = (a-b)(a+b)

so for the thing above you have

(a-5)^2 - 36 = (a-5)^2 - 6^2 = (a-5-6)(a-5+6) = (a-11)(a+1).

Ahhh. I think I can see it. You're a gem G.
