How do you factor this: 8(3a7)^2+2(3a7)45 ? I tried Mathway and the answer was this: 3(2a3)(12a37) But I have no idea how it came up with that. Help me please. Thank you.

hi , Gelatine.. If the situation were something like... 8(3a7)^2 + 2(3a7), then, can I calculate this like .. 8+2 , (3a7) + ( 3a7) ? so it will be 10{(3a7)+(3a7)} ?

No, since you have square of (3a7)
