Question

Can someone please factor this fully? My friend and I have two different answers and i would like to know if either of them is right. Thank you in advance.

a^2 - b^2 + 25 + 10a

Answer 1

(a+5) (a+5) - b²

Explanation:

a²+10a+25-b² = (a-5) (a-5) ..easy XD

-b² stays constant ..obviously XD
