Question

Find the general solution:
9y''-12y'+4y=0

Answer 1

\[9m^2-12m+4=0\]

Answer 2

can u factorize this polynomial ?

Answer 3

(3m+2)(3m+2)

Answer 4

@mustafa2014

Answer 5

ok

Answer 6

(3m-2)(3m-2)=0

Answer 7

minus not plus

Answer 8

3m=2 >>> m=2/3 , m=2/3

Answer 9

\[y _{c}=C _{1}+xC _{2}e ^{mx}\]

Answer 10

y = C1+xC2e^(2/3)x ?

Answer 11

Yep

Answer 12

wait

Answer 13

\[y _{c}=C _{1}e ^{mx}+xC _{2}e ^{mx}\]

Answer 14

C1 times e^mx

Answer 15

y=C1e^(2/3)x + xC2e^(2/3)x

Answer 16

correct :)

Answer 17

Thank you, can we do another?
