Answer 1

Any ideas? Hint: a difference of squares can be factored into the sum of two numbers times their difference.

Answer 2

Hey!

Ok first we write 36 as a square in order to express x2-36 as a difference squares

so what do we get?

Answer 3

so we are just writing 36 as a square

Answer 4

I barley started learning this, since a square is 4 is it 36/4? Im just taking a guess?

Answer 5

v^2 — 36 = v^2 — 6^2

Answer 6

Well it was like this 6^2 before right? so they put it into this 36 b.c 6^2=36 so now they want it back to 6^2

Answer 7

you get it @ninowletonzalez06

Answer 8

so if we put it back to 6^2 we get
\[v ^{2}-6^{2}\]

Answer 9

Have you studied the FOIL method?

Answer 10

so im thinking it will be A or D?

Answer 11

Good so net we factor the difference of two squares

Answer 12

next*

Answer 13

so we factor the difference of two square and what do we get

Answer 14

since the symbol is subtraction it should be D since both of the signs are (-)

Answer 15

Nope its not b.c we factoring the difference

Answer 16

your on the right track :D

Answer 17

can you explain on the drawing tool?

Answer 18

Try using the distributive property.

Answer 19

So what do we do next?
