Question

please help me factor: (D^3 - 3D^2 + 4)

Answer 1

*sigh* factoring differential equations =_= i always hated these stuffs :/

Answer 2

yuuuup!

Answer 3

how would (D-2)^2(D+1)?

Answer 4

sound*?

Answer 5

that would be

(D-2)(D-2) = D^2 - 2D + 4

(D^2-2D+4)(D+1) = D^3 -2D^2 + 4D + 1 right?

Answer 6

-4D in top part, right?

Answer 7

D(2) = 0 right?

unless you're doing this algebraically..

Answer 8

even so, isnt (d-2)^2 = d^2 - 4d +4?
