Question

c^2-6cd+9d^2-4 Factor this expression as a difference of squares...

Answer 1

are you a genius?

Answer 2

c(c-6d)+(3d-2)(3d+2) ... hmm this way doesn't work

Answer 3

Of course it does ^

Answer 4

\( \color{Black}{\Rightarrow (a + b)(a - b) = a^2 - b^2 \Longrightarrow (3d - 2)(3d + 2) = (3d)^2 - (2)^2}\)

Answer 5

No, there's also the front part

Answer 6

OOPSIE

Answer 7

Well anyway let's start by doing \(c(c - d) + (9d^2 - 4)\)

Answer 8

c^2-4-6cd+9d^2
(c-2)(c+2)-6cd+9d^2

Answer 9

Oh yup

Answer 10

ok if we pull out a 3d:
(c-2)(c+2)+3d(3d-2c)

Answer 11

still not working.. ohhhh complete the square.. lol

Answer 12

I really appreciate your help Agent47 :)

Answer 13

c^2-6cd+9d^2-4
DUHHHH LOL I got it

Answer 14

I love you chloe! lol

Answer 15

factor the first part:
(c-3d)^2-4

Answer 16

(c-3d)^2-2^2

Answer 17
