you got the second one right but the first one is -2-8i

I dont know the first one but the second one is just -i

you are right with number 1 and 3 but the second one is just 4

never mind i found the answer its 1 btw

9 = (r-2)(2r+sqrt5)(2r-sqrt5)

10 = (7k+6)(3k^2+8)

11 = (6x+7)(sqrt7x+sqrt6)(sqrt7x-sqrt6)

12 = (p+6)(p+sqrt3)((p-sqrt3)

I think the answer is 2/5

thx CPhill

:)

the answer is t=-19/15 and s =-32/15

so the answer is (-19/15,-32/15)

thanks CPhill

thanks!
