Angle:

I posted the formula for the difference of squares

narutouzamaki2:

which one do u think it is

Angle:

The difference of squares is: (a number or variable) to the second power MINUS (another number or variable) also to the second power

mw104969:

so I think the first a is one of them

Angle:

@mw104969 A is incorrect. This is because (x - 36)^2 expands into x^2 - 72x + 1296 which has 3 terms and is therefore not a difference of squares

person321:

yeah, all i got rn is A

Angle:

option A is incorrect

xxDeppressionxx:

Yes it is

Angle:

@xxDeppressionxx what do you mean?

person321:

is it just A then?

xxDeppressionxx:

No option a is incorrect

person321:

oh

Angle:

Angle:

@xxDeppressionxx Option E is INCORRECT because that is not a "difference". A "difference" is referring to the MINUS operation you have a PLUS sign there in option E

person321:

so its... b and c?

Angle:

Does option B had a PLUS sign? what did I just say about Plus signs?

person321:

oh yeah so just c?

Angle:

I think so

xxDeppressionxx:

Oh wait option b is correct because it is a perfect square

xxDeppressionxx:

I think there are two answers

xxDeppressionxx:

B and C

person321:

thank you guys, that was helpful :)
