its A

@123666 how do I explain that???

try multiplying them all out

I need to explain it and all of its steps and I'm not sure how to do that

multiply the first two out

and then what?

Work
2(1+2) = 6
(1+2)^2 = 9
2^2 + 1^2 = 5
2^2 - 1^2 = 3

then compare them. what did you get?

*when you multiplied

they are the same except one is multiplying by 2 and the other is multiplying by ^2

Step by step Im pretty sure

One is multiplying by 2 and the other is squaring the answer. It makes a big difference

yep! I see now how you got that.

i didn't mean they ARE the same i meant they LOOK the same exceptt for that

tbh @Utterly_Confuzzled strategy is what you would want to use on the actual ACT

yeah, true. ok! So thats basically how I would solve the problem???

what @Utterly_Confuzzled said ? And it is B?

yeah. Is plugging in numbers what you're looking for in the way of an explanation.

Yes it's B
And I think they meant finding two numbers that work and just plugging them in

Okay! Thanks to both of you

okay, but what utterly said should be sufficient?? In explaining my answer?

I guess.

@peachpi is right, it's normally safest not to use 0 or 1
And I believe it should suffice.

Its for a grade but its ACT prep...

@peachpi this is how Id solve the problem

yeah just plug in numbers

sounds good?

yes

ok- thanks again for your help:-)

well you want to say you plugged them into all four options and B was the highest

okay. Thanks, that helped!
