Answer 1

So the first step is we have to find out what is a factor that can be squared, right?

Answer 2

good! any ideas on what we can factor out?

Answer 3

12 and 20?

Answer 4

12 and 20 are not perfect squares, so they're not good choices

Answer 5

hint:

240 = 100 * 4 * 6

Answer 6

ohhh riiight

Answer 7

100 and 24?

Answer 8

square root of 10

Answer 9

so, after you factor out 100 you get

10 * sqrt(24)

Answer 10

this is your answer

(although you could technically simplify that to 20sqrt(6), this isn't one of the answer choices)

Answer 11

Right?
