Answer 1

try substituting u=sin(x)
with that, you'd have..
\[ 6u^2 - 7u + 2 = 0 \]
you can solve for u by factoring and then back-substitute for equations in the form "sin x = ..."

Answer 2

it can be (x+3 ) (x+6) =0 or
(x+9/2) -9/4 =0

Answer 3

ok i got u=-2/3 and u=-1/2

Answer 4

what's next?

Answer 5

hmm.. can you show what you did? I get u=2/3 and u=1/2
6u^2 - 4u - 3u + 2 = 0
2u(3u - 2) - (3u - 2) = 0
(3u - 2)(2u - 1) = 0
3u - 2 = 0 2u - 1 = 0
3u = 2 2u = 1
u = 2/3 u = 1/2

Answer 6

oops nvm i got it thx for ur time! :P

Answer 7

No problem. :)
