Question

Either A or B Im thinking its B

Answer 1

Which shows 532 - 472 being evaluated using the difference of squares method?

532 - 472 = 2809 - 2209 = 600

532 - 472 = (53 + 47)(53 - 47) = (100)(6) = 600

532 - 472 = (53 - 47)2 = 62 = 36

532 - 472 = (2809 + 2209)(2809 - 2209) = 3,010,800

Answer 2

53^2 - 47^2

Answer 3

oh ok that makes sense now xD

Answer 4

nvm

Answer 5

look at the expansion of those brackets

Answer 6

have you learnt foil method?

Answer 7

yea but I really didn't get the hang of it...

Answer 8

(53 + 47)(53 - 47)=53^2 +47*53 - 47*53 -47^2=53^2-47^2

Answer 9

$$\Huge a^2-b^2=?$$

Answer 10

600

Answer 11

Well its nothing really, you dont need to understand foil method, just how to explain brackets

Answer 12

Thank You @dan815 !

Answer 13

So I was right right?

Answer 14

expand* brackets and yes B is right

Answer 15

Ok thank you again!
